Neutron spin echo (NSE) spectroscopy is the highest energy resolution neutron scattering technique available for examining a large area (in time and space) in condensed matter physics. This broad dynamic and spatial range is extensively exploited in the study of a wide range of scientific problems ranging from the dynamics of glasses, polymer melts, complex fluids and microemulsions to the elementary excitations in superfluid 4He and to ferromagnets and spin glasses. This book reviews the current status and future prospects in NSE spectroscopy describing the method, latest instrumentation and also the use of NSE in fundamental, hard- and soft-matter science. It provides first-hand information for researchers working in the fields touched by NSE. In addition, young researchers, PhD students and graduates interested in the method will obtain a comprehensive overview and guidelines to implementing the NSE technique.
This book, entitled Electrochemistry of Glasses and Glass Melts - Including Glass Electrodes, is one of a series reporting on research and development activities on products and processes conducted by the Schott Group. The scientifically founded development of new products and technical pro- cesses has traditionally been of vital importance to Schott and has always been performed on a scale determined by the prospects for application of our special glasses. Since the reconstruction of the Schott Glaswerke in Mainz, the scale has increased enormously. The range of expert knowledge required could never have been supplied by Schott alone. It is also a tradition in our company to cultivate collaboration with customers, universities, and research institutes. Publications in numerous technical journals, which since 1969 we have edited to a regular schedule as Forschungsberichte - "e;research reports"e; - describe the results of these cooperations. They contain up-to-date infor- mation on various topics for the expert but are not suited as survey material for those whose standpoint is more remote. This is the point where we would like to place our series, to stimulate the exchange of thoughts, so that we can consider from different points of view the possibilitiel:l offered by those incredibly versatile materials, glass and glal:ls ceramics.
Complex systems are ubiquitous, and practically all branches of science ranging from physics through chemistry and biology to economics and sociology have to deal with them. In this book we wish to present concepts and methods for dealing with complex systems from a unifying point of view. Therefore it may be of inter- est to graduate students, professors and research workers who are concerned with theoretical work in the above-mentioned fields. The basic idea for our unified ap- proach sterns from that of synergetics. In order to find unifying principles we shall focus our attention on those situations where a complex system changes its macroscopic behavior qualitatively, or in other words, where it changes its macroscopic spatial, temporal or functional structure. Until now, the theory of synergetics has usually begun with a microscopic or mesoscopic description of a complex system. In this book we present an approach which starts out from macroscopic data. In particular we shall treat systems that acquire their new structure without specific interference from the outside; i. e. systems which are self-organizing. The vehicle we shall use is information. Since this word has several quite different meanings, all of which are important for our purpose, we shall discuss its various aspects. These range from Shannon information, from which all semantics has been exorcised, to the effects of information on receivers and the self-creation of meaning.
The scanning probe microscopy ?eld has been rapidly expanding. It is a demanding task to collect a timely overview of this ?eld with an emphasis on technical dev- opments and industrial applications. It became evident while editing Vols. I-IV that a large number of technical and applicational aspects are present and rapidly - veloping worldwide. Considering the success of Vols. I-IV and the fact that further colleagues from leading laboratories were ready to contribute their latest achie- ments, we decided to expand the series with articles touching ?elds not covered in the previous volumes. The response and support of our colleagues were excellent, making it possible to edit another three volumes of the series. In contrast to to- cal conference proceedings, the applied scanning probe methods intend to give an overview of recent developments as a compendium for both practical applications and recent basic research results, and novel technical developments with respect to instrumentation and probes. The present volumes cover three main areas: novel probes and techniques (Vol. V), charactarization (Vol. VI), and biomimetics and industrial applications (Vol. VII). Volume V includes an overview of probe and sensor technologies including integrated cantilever concepts, electrostatic microscanners, low-noise methods and improved dynamic force microscopy techniques, high-resonance dynamic force - croscopy and the torsional resonance method, modelling of tip cantilever systems, scanning probe methods, approaches for elasticity and adhesion measurements on the nanometer scale as well as optical applications of scanning probe techniques based on near?eld Raman spectroscopy and imaging.
A survey of recent research in the fields of condensed matter physics and chemistry based on novel NMR and ESR techniques. Applications include quantum computing, metal nanoparticles, low dimensional magnets, fullerenes as atomic cages, superconductors, porous media, and laser assisted studies. The book is dedicated to Professor Robert Blinc, on the occasion of his seventieth birthday, in appreciation of his remarkable scientific accomplishments in the NMR of condensed matter.
This book presents theoretical as well as experimental articles focused on recent new results in high temperature superconductivity. All contributors are high ranking scientists who have done major work to enhance the understanding of this phenomenon. A few articles deal with ferroelectricity and its applications. The book is dedicated to Prof. Dr. K. Alex Muller on his 80th birthday. During his scientific career he made major advances in the understanding of ferroelectricity.
Historically, quasi-low-dimensional superconductors were considered as the main candidates to observe high-temperature superconductivity. For a disc- sion of the related exotic mechanisms of superconductivity, suggested by W.A. Little and V.L. Ginzburg, see a chapter by D. J¿ erome in this volume. Unf- tunately, high-temperature superconductivity has not been discovered yet in quasi-one-dimensional (Q1D) and quasi-two-dimensional (Q2D) organic ma- rials. Nevertheless, very rich and, in many cases, unique physical properties of their metallic, superconducting, charge- and spin-density-wave phases allowed P.M. Chaikin to claim that the ?rst organic superconductors, (TMTSF) X, 2 are probably the most interesting electronic materials ever discovered. Our book welcomes a reader to a fascinating world of exotic condensed matter physics, low temperatures, and high and ultrahigh magnetic ?elds. It is written by leading experts in the area from USA, France, Japan, Russia, United Kingdom, Germany, Canada, South Korea, Croatia, Hungary, and Switzerland. The book consists of six parts, subdivided into 27 chapters, which contain both the experimental results and their theoretical explanations. The majority of the chapters contain pedagogical introductions and all necessary illustrations to be read separately. Although we concentrate on physical p- nomena, in the most chapters related chemistry and structural aspects of Q1D and Q2D organic materials are also discussed.
This volume contains papers presented at the 8th International Conference on Solid State Physics (SSP 2004), Workshop "Mössbauer Spectroscopy of Locally Heterogeneous Systems", held in Almaty, Kazakhstan, 23¿26 August 2004.It should be of interest to researchers and PhD students working or interested in recent results in the locally inhomogeneous system investigations by Mössbauer Spectroscopy and the new concepts of data evaluation of complex Mössbauer spectra.
The book covers the flux pinning mechanisms and properties and the electromagnetic phenomena caused by the flux pinning common for metallic, high-Tc and MgB2 superconductors. The condensation energy interaction known for normal precipitates or grain boundaries and the kinetic energy interaction proposed for artificial Nb pins in Nb-Ti, etc. are introduced for the pinning mechanism. Summation theories to derive the critical current density are discussed in detail. Irreversible magnetization and AC loss caused by the flux pinning are also discussed. The loss originally stems from the ohmic dissipation of normal electrons in the normal core driven by the electric field induced by the flux motion.The readers will learn why the resultant loss is of hysteresis type in spite of such mechanism. The influence of the flux pinning on the vortex phase diagram in high Tc superconductors is discussed and the dependencies of the irreversibility field are also described on other quantities such as anisotropy of superconductor, specimen size and electric field strength. Recent developments of critical current properties in various high-Tc superconductors and MgB2 are introduced.Other topics are: singularity in the case of transport current in a parallel magnetic field such as deviation from the Josephson relation, reversible flux motion inside pinning potentials which causes deviation from the critical state model prediction, the concept of the minimization of energy dissipation in the flux pinning phenomena which gives the basis for the critical state model, etc. Significant reduction in the AC loss in AC wires with very fine filaments originates from the reversible flux motion which is dominant in the two-dimensional pinning. The concept of minimum energy dissipation explains also the behavior of flux bundle size which determines the irreversibility line under the flux creep.The new edition has been thoroughly updated, with new sections on the progress in enhancing the critical current density in high temperature superconductors by introduction of artificial pinning centers, the effect of packing density on the critical current density and irreversibility field in MgB2 and derivation of the force-balance equation from the minimization of the free energy including the pinning energy.
Modern science and technology, from materials science to integrated circuit development, is directed toward the nanoscale. From thin films to field effect transistors, the emphasis is on reducing dimensions from the micro to the nanoscale. Fundamentals of Nanoscale Film Analysis concentrates on analysis of the structure and composition of the surface and the outer few tens to hundred nanometers in depth. It describes characterization techniques to quantify the structure, composition and depth distribution of materials with the use of energetic particles and photons.The book describes the fundamentals of materials characterization from the standpoint of the incident photons or particles which interrogate nanoscale structures. These induced reactions lead to the emission of a variety of detected of particles and photons. It is the energy and intensity of the detected beams that is the basis of the characterization of the materials. The array of experimental techniques used in nanoscale materials analysis covers a wide range of incident particle and detected beam interactions.Included are such important interactions as atomic collisions, Rutherford backscattering, ion channeling, diffraction, photon absorption, radiative and nonradiative transitions, and nuclear reactions. A variety of analytical and scanning probe microscopy techniques are presented in detail.
The frontiers in scientific research are difficult to define. Nowadays the new knowledge depends not only on new methods and concepts but also on the interaction with other fields of research. Biophysics offers a rational language for discussion among scientists of different disciplines. This is the general philosophy behind the organization of the Summer Schools organized by Rudjer Boskovi ? Institute, Zagreb, Croatia and the Croatian Biophysical Society from 1981 on each third year. Internationally recognized and successfully established nine international summer schools have been organized under the title Supramolecular Structure and Function The International Summer Schools on Biophysics have a very broad scope devoted to the structure-function relationship of biological macromolecules and to mayor biophysical techniques. The int- tion is to organize courses which provide advanced training at doctoral or postdoctoral level in biosciences. Sixteen main contributions presented here by prominent lecturers illustrate the principals, concepts and methods of b- physics coupled with molecular biology approaches. Since the great diversity of topics the book should be of interest for scientists of different disciplines as was the audience at the School.
