Available in PDF, EPUB and Kindle. Book excerpt: This family of intermetallic compounds is ideal for the study of the interplay between superconductivity and magnetism since, in several of these compounds (Ho, Er, Tm, Dy), superconductivity coexists with magnetic ordering. The most important findings of the scattering studies are (a) in the Ho-compound, a complex magnetic structure characterized by two incommensurate wave vectors, {rvec k}{sub a} = 0.585 {rvec a}* and {rvec k}{sub c} = 0.915 {rvec c}*, exists in the vicinity of 5 K, where the almost reentrant behavior of this compound occurs; (b) an incommensurate magnetic structure with wave vector along {rvec a}*, close to the zone boundary, is observed in several of these compounds; and (c) pronounced soft-phonon behavior was observed for both the acoustic and first optical [Delta]4[[xi]00] branches in the superconducting Lu and Ho compounds, a behavior characteristic of strongly coupled conventional superconductors. Furthermore, these phonon anomalies occur at wave vectors close to those of the incommensurate magnetically ordered structures observed in the magnetic compounds of this family. This observation suggests that both the magnetic ordering and phonon softening originate from common nesting features of the Fermi surfaces of these compounds. Band theoretical calculations are in qualitative agreement with these results.

Download or read book Complementarity Between Neutron And Synchrotron X-ray Scattering - Proceedings Of The Sixth Summer School Of Neutron Scattering written by Albert Furrer and published by World Scientific. This book was released on 1998-12-30 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding and manipulating the properties of materials naturally occurring in our world and artificially produced by modern technologies requires detailed information on their properties on the atomic scale. This information is the basis for any kind of research in physics, chemistry, biology, engineering, metallurgy, and ceramics. Among the various experimental methods, neutron and photon scattering have become the key techniques of choice.This book provides an overview of the complementarity between neutron and synchrotron x-ray scattering. The most important topics are covered, including structure determination, magnetic correlations, polymer dynamics, thin films and multilayers, photoemission studies, etc; they are thoroughly introduced and discussed by experts from both the experimental and the theoretical side.

Book excerpt: By browsing about 10 000 000 scientific articles of over 200 major journals mainly in a 'cover to cover approach' some 200 000 publications were selected. The extracted data is part of the following fundamental material research fields: crystal structures (S), phase diagrams (also called constitution) (C) and the comprehensive field of intrinsic physical properties (P). This work has been done systematically starting with the literature going back to 1900. The above mentioned research field codes (S, C, P) as well as the chemical systems investigated in each publication were included in the present work. The aim of the Inorganic Substances Bibliography is to provide researchers with a comprehensive compilation of all up to now published scientific publications on inorganic systems in only three handy volumes.

Book Synopsis Neutron and X-ray Scattering Studies of Disorder in Quantum Materials by : Mingde Jiang
Download or read book Neutron and X-ray Scattering Studies of Disorder in Quantum Materials written by Mingde Jiang and published by . This book was released on 2022 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantum materials generally refer to condensed matter systems whose properties are dictated by strongly interacting quantum mechanical effects. This includes many classes of materials at the forefront of condensed matter research, for example high temperature superconductors, quantum spin liquids, and many others. In addition to hosting their eponymous phases, frequently these materials also exhibit competing ground states, where minute parameter changes lead to qualitatively different phases. The existence of atomic scale disorder is often sufficient to alter the ground state of many such systems. Experimentally, disorder is an inherent component of real (and in particular, bulk) materials, commonly due to imperfections in synthesis and intentional introduction of substitution/dopant atoms. It is therefore important to characterize and model the disorder in such materials to fully understand their physics. The nature and time/length scales of disorder varies significantly between different materials, requiring specifically tailored techniques. This thesis details innovative neutron and x-ray scattering studies on several quantum materials of current interest with distinct types of disorder relevant to high temperature superconductivity and quantum spin liquids.
