Описание: This book focuses on the characterisation of the chiral and topological nature of magnetic skyrmions in noncentrosymmetric helimagnets. In these materials, the skyrmion lattice phase appears as a long-range-ordered, close-packed grid of nearly millimetre-level correlation length, while the size of a single skyrmion is 3–100 nm. This is a very challenging range of length scales (spanning 5 orders of magnitude from tens of nm to mm) for magnetic characterisation techniques, and, to date, extensive information on this fascinating, magnetically ordered state has remained elusive. In response, this work develops novel resonant elastic x-ray scattering (REXS) techniques, which allow the magnetic structure, including the long-range order and domain formation, as well as microscopic skyrmion parameters, to be measured across the full range of length scales. Most importantly, using circular dichroism in REXS, the internal structure of a given skyrmion, the topological winding number, and the skyrmion helicity angle can all be unambiguously determined. These new techniques are applicable to many materials systems, and allow us to retrieve information on modulated spin structures, multiferroic order, spin-density-waves, and other forms of topological magnetic order.

Описание:
"The book reviews all the aspects of recent developments in research on skyrmions, from the presentation of the observation and characterization techniques to the description of physical properties and expected applications. It will be of great use for all scientists working in this field." - Albert Fert, 2007 Nobel Laureate in Physics (from the Foreword)
A skyrmion is a tiny region of reversed magnetization - quasiparticles since they are not present except in a magnetic state, and also give rise to physics that cannot be described by Maxwell's equations. These particles are fascinating subjects for theoretical and experimental studies. Moreover, as a new type of magnetic domain structure with special topological structures, skyrmions feature outstanding magnetic and transport properties and may well have applications in data storage and other advanced spintronic devices, as readers will see in this book. Chapters address the relationships between physical properties of condensed matter, such as the AB effect, Berry phase effect, quantum Hall effect, and topological insulators. Overall, it provides a timely introduction to the fundamental aspects and possible applications of magnetic skyrmions to an interdisciplinary audience from condensed matter physics, chemistry, and materials science.

Описание: This brief reviews current research on magnetic skyrmions, with emphasis on formation mechanisms, observation techniques, and materials design strategies.
Описание: During the past century, world-wide energy consumption has risen dramatically, which leads to a quest for new energy sources. Fusion of hydrogen atoms in hot plasmas is an attractive approach to solve the energy problem, with abundant fuel, inherent safety and no long-lived radioactivity.

Описание: In the last decade after the discovery of "giant magnetoresistance effects" in me- tallic multilayers worldwide developments in basic research and in engineering applications have been achieved, and various remarkable results have been ob- tained in both fields. On the basic research into the GMR effects an excellent re- view book edited by Hartmann was published in 1999, entitled "Magnetic Multi- layers and Giant Magnetoresistance," and it describes the experimental and theoretical aspects of GMR studies and the magneto-optics in metallic multilayers, including applications in electronic data storage fields. This book aims to give an overview on the electronics applications of the GMR in metallic multilayers, espe- cially on the sensors and memories in magnetic data storage, the main concerns of electronic engineers. If the mean free path of conduction electrons is longer than the period of the multilayer, and for a low applied magnetic field magnetizations in the adjacent magnetic layers are in antiparallel, the GMR effect in magnetic metallic multilay- ers occurs due to the resistance change in the electric current flowing in the layer plain, with a change in the magnetization from antiparallel to parallel alignment by an applied magnetic field (CIP mode), i. e., in the saturation field magnetiza- tions are in parallel and the resistance is lowered. The saturation field H, is given by the RKKY-like magnetic coupling between adjacent magnetic layers through a nonmagnetic conductive layer between the layers.

Описание:
This pioneering monograph solely deals with the Magneto Thermoelectric Power (MTP) in Heavily Doped (HD) Quantized Structures. The materials considered range from HD quantum confined nonlinear optical materials to HgTe/CdTe HD superlattices with graded interfaces and HD effective mass superlattices under magnetic quantization. An important concept of the measurement of the band gap in HD optoelectronic materials in the presence of external photo-excitation has been discussed in this perspective. The influences of magnetic quantization, crossed electric and quantizing fields, the intense electric field on the TPM in HD semiconductors and superlattices are also discussed. This book contains 200 open research problems which form the integral part of the text and are useful for both PhD aspirants and researchers in the various fields for which this particular series is dedicated.
