Download or read book Magnetic Phase Transitions In Single Crystals written by Daivd P Belanger and published by World Scientific. This book was released on 2022-07-27 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Magnetic crystals are ideal systems to study the universal properties of phase transitions, particularly systems with quenched randomness and frustration. Pure systems with different symmetries provide the foundation for studies in corresponding systems with quenched randomness. Because phenomena near phase transitions have universal properties, results from bulk magnetic crystals provide a basis for understanding phase transitions in films and nanoparticles, as well as many non-magnetic materials.This motivates the subject of this book, which discusses phase transitions studies in magnetic crystals from the perspective of an experimentalist who has done extensive work in the field. The advantage is that many experimental techniques are described in sufficient detail for a good understanding of the results and their comparison to theory.

Available in PDF, EPUB and Kindle. Book excerpt: The present volume contains the courses given at a Summer School on "Magne tic Phase Transitions" held at the Ettore Majorana Centre for Scientific Culture, at Erice (Trapani), Italy in July 1983 under the auspices of the Condensed Matter Division of the European Physical Society in their series on Materials Science and Technology. The student participants came from West Germany, Great Britain, Brazil, Greece, Switzerland, Sweden, Italy, USA and The Netherlands. The lecturers came from various European countries, Israel, USA and Canada. The atmosphere at the meeting was excellent and a good spirit of companion ship developed during two weeks of working together. The spread of interests among the lecturers and students was divers;jfied but balanced. The main lec turing contributions are reported in this volume. They represent up-to-date reviews in a pedagogical style. In addition, informal presentations on cur rent research interests were made which have not been included. The school attempted to summarize the current position on the properties of magnetic phase transitions from several points of view. The range and scope of the oretical techniques, and of particular aspects of materials or phenomena as observed experimentally were very well put forward by the lecturers. The grouping of manuscripts in chapters does not represent, however, the sched ule followed during the school. Contributions on mean-field approximations and renormalization-group methods either for static or dynamic phenomena can be found at various places in the following sections.
Download or read book Phase Diagram and Magnetic Excitations of BaFe2 xNixAs2 A Neutron Scattering Study written by Xingye Lu and published by Springer. This book was released on 2017-07-10 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book studies the structural, magnetic and electronic properties of, as well as magnetic excitations in, high-temperature BaFe2-xNixAs2 superconductors using neutron diffraction and neutron spectroscopic methods. It describes the precise determination of the phase diagram of BaFe2-xNixAs2, which demonstrates strong magnetoelastic coupling and avoided quantum criticality driven by short-range incommensurate antiferromagnetic order, showing cluster spin glass behavior. It also identifies strong nematic spin correlations in the tetragonal state of uniaxial strained BaFe2-xNixAs2. The nematic correlations have similar temperature and doping dependence as resistivity anisotropy in detwinned samples, which suggests that they are intimately connected. Lastly, it investigates doping evolution of magnetic excitations in overdoped BaFe2-xNixAs2 and discusses the links with superconductivity. This book includes detailed neutron scattering results on BaFe2-xNixAs2 and an introduction to neutron scattering techniques, making it a useful guide for readers pursuing related research.

Download or read book Topological Structures in Ferroic Materials written by Jan Seidel and published by Springer. This book was released on 2016-02-12 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a state-of-the art overview of a highly interesting emerging research field in solid state physics/nanomaterials science, topological structures in ferroic materials. Topological structures in ferroic materials have received strongly increasing attention in the last few years. Such structures include domain walls, skyrmions and vortices, which can form in ferroelectric, magnetic, ferroelastic or multiferroic materials. These topological structures can have completely different properties from the bulk material they form in. They also can be controlled by external fields (electrical, magnetic, strain) or currents, which makes them interesting from a fundamental research point of view as well as for potential novel nanomaterials applications. To provide a comprehensive overview, international leading researches in these fields contributed review-like chapters about their own work and the work of other researchers to provide a current view of this highly interesting topic.

Available in PDF, EPUB and Kindle. Book excerpt: The crystallographic and magnetic properties for the M[N(CN)2]2 (M = Mn, Fe, Co, Ni) series have been investigated by neutron diffraction, dc magnetization, ac susceptibility and specific heat on polycrystalline samples. The crystal structures for all compounds are isomorphous in the paramagnetic regime as well as in the ordered state, and consist of discrete octahedra which are axially elongated and successively tilted in the ab-plane. The zero-field magnetic structure for the Mn and Fe compounds consists of two sublattices which are antiferromagnetically coupled and spontaneously canted, with spin orientation mainly along the a-axis. There is a small uncompensated moment along the b-axis (Mn) and the c-axis (Fe). The zero-field magnetic structure for the Co and Ni compounds is collinear ferromagnetic with spin orientation along the c-axis. The results provide the first determination of a complete magnetic structure in the ordered state for a molecule-based magnet. The ground states are characterized by large magnetic anisotropy. The application of a magnetic field induces a spin rotation transition in the Mn compound and an energy-level crossing in the Fe compound. The dc magnetization and in-field specific heat studies for Cu[N(CN)2]2 reveal the previously unknown ferromagnetic ordering at low temperatures. Comparisons of the magnetic structures for the isostructural M[N(CN)2]2 (M = Mn, Fe, Co, Ni) series suggest that the spin direction is stabilized by crystal fields and the spin canting is induced by the successive tilting of the octahedra. We propose that the superexchange interaction is the mechanism responsible for the magnetic ordering in these compounds and we find that a crossover from noncollinear antiferromagnetism to collinear ferromagnetism occurs for a superexchange angle of [alpha]c = 142.0(5)°.

Book excerpt: During the period February 1, 1968 to December 31, 1971, the Principal Investigator and his research group carried out a number of detailed experimental studies of the behavior of magnetic spin systems at temperatures close to the magnetic ordering critical point. The principal experimental techniques employed were Nuclear Magnetic Resonance and Neutron Scattering. The experiments of the former type were carried out at Brandeis University. Those of the latter type were carried out at the High Flux Beam Reactor at the Brookhaven National Laboratory. With reference to the NMR EXPERIMENTS4 SOME ADDITIONAL WORK WAS ALSO DONE AT THE National Magnet Laboratory at the Massachusetts Institute of Technology. (Author).

This book was released on 2019-08-14 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides extensive and novel insights into transport phenomena in MnSi, paving the way for applying the topology and chirality of spin textures to the development of spintronics devices. In particular, it describes in detail the key measurements, e.g. magnetoresistance and nonlinear electronic transport, and multiple material-fabrication techniques based on molecular beam epitaxy, ion-beam microfabrication and micromagnetic simulation. The book also reviews key aspects of B20-type MnSi chiral magnets, which host magnetic skyrmions, nanoscale objects formed by helical spatial spin structures. Readers are then introduced to cutting-edge findings on the material. Furthermore, by reviewing the author’s successful experiments, the book provides readers with a valuable update on the latest achievements in the measurement and fabrication of magnetic materials in spintronics.
