Download or read book Ferroics and Multiferroics written by Hardev Singh Virk and published by . This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume is indexed by Thomson Reuters BCI (WoS).Multiferroics: that is, materials which simultaneously exhibit both ferromagnetism and ferroelectricity - and also often ferroelasticity - now attract considerable attention because of the interesting physics involved and their promise for important practical applications. Typical multiferroics belong to the perovskite group of transition metal oxides, and include rare-earth manganites and ferrites. Several new multiferroic systems have been developed, during recent years, which exhibit very strong coupling between the ferroelectric and magnetic degrees of freedom. The present volume comprises both review articles, and research papers on various themes; with very little overlap. The authors of the review papers have generally kept in mind the unfamiliarity, of the field of 'Ferroics and Multiferroics', to newcomers. They cover the historical development of the field, and add their own contributions.

Available in PDF, EPUB and Kindle. Book excerpt: The present book is the second edition of Amikam Aharoni's Introduction to the Theory of Ferromagnetism, based on a popular lecture course. Like its predecessor, it serves a two-fold purpose: First, it is a textbook for first-year graduate and advanced undergraduate students in both physics and engineering. Second, it explains the basic theoretical principles on which the work is based for practising engineers and experimental physicists who work in the field of magnetism, thus also serving to a certain extent as a reference book. For both professionals and students the emphasis is on introducing the foundations of the different subfields, highlighting the direction and tendency of the most recent research. For this new edition, the author has thoroughly updated the material especially of chapters 9 ('The Nucleation Problem') and 11 ('Numerical Micromagnetics'), which now contain the state of the art required by students and professionals who work on advanced topics of ferromagnetism. From reviews on the 1/e: '... a much needed, thorough introduction and guide to the literature. It is full of wisdom and commentary. Even more, it is Amikam Aharoni at his best - telling a story... He is fun to read... The extensive references provide an advanced review of micromagnetics and supply sources for suitable exercises... there is much for the student to do with the guidance provided by Introduction to the Theory of Ferromagnetism.'

Download or read book Exploring Magnetism in Van Der Waals 2D Materials and Heterostructures written by Ya Wen Chuang and published by . This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the successful isolation of graphene in 2004, 2D van der Waals materials have drawn a lot of interests of the community because of their potential in advancing fundamental physics understandings and next-generation device applications. Van der Waals materials with diverse properties have been synthesized and studied and many fundamental phenomena of condensed matter physics including the quantum Hall effect, superconductivity, and magnetism have been observed. Robust room-temperature 2D magnetism remains a goal of the field. We have explored three van der Waals 2D materials to realize magnetism. This includes bilayer graphene, gallium selenide (GaSe), and manganese bismuth telluride (MnSb1.8Bi0.2Te4). A strain-tuning technique based on a piezoelectric substrate is developed and will offer convenient tuning of magnetic properties. This dissertation begins with an introduction, which is followed by four chapters, each of which discusses a material platform or technique. Chapter 1 gives an overview of the properties of 2D materials, which forms the basis of our investigations in the following chapters. We discuss different ways to manipulate the properties of 2D materials. Chapter 1 also gives a brief introduction on the current state of magnetism in 2D. Chapter 2 presents findings in WSe2/bilayer graphene heterostructures. Our original goal was to introduce spin-orbit coupling into bilayer graphene through proximity coupling. The effect was found to be very small. Instead we observed large modifications to the Landau level energies of bilayer graphene, which suggests a possible way to engineer the quantum Hall effect. A systematic study of Landau level gaps at filling factors [nu] = 1, 2, 3 is presented and offers insight to the rich competing many-body interactions in bilayer graphene. Chapter 3 describes our effort in making electrical contacts to GaSe using various materials and procedures. We also discuss different fabrication ideas to enhance the quality of GaSe devices. Our original goal was to study the predicted gate-tunable ferromagnetism in few-layer GaSe. We were not successful in the end however this work provides valuable information to the challenging problem of contacting thin GaSe flakes. Chapter 4 reports our observations of a ferromagnetic ground state in MnSb1.8Bi0.2Te4, a van der Waals magnetic compound. This work was done with collaborators in synthesis and structural characterizations. The development of ferromagnetism in MnSb1.8Bi0.2Te4, in contrast to commonly observed anti-ferromagnetism in this family of materials, is supported by magneto-transport measurements, bulk magnetometry and neutron scattering. Our finding contributes to the understanding of a newly discovered family of ferromagnetic topological insulators. Chapter 5 describes our design and fabrication of a strain-tuning substrate that is based on piezoelectric lead zirconate titanate (PZT) and suitable for devices made of van der Waals materials. Strain is a powerful tool for manipulating 2D material properties, including magnetism. Our substrate integrates strain tuning, Al2O3 gating, ionic liquid gating, and electrical measurement capabilities. We aim for a platform compatible with cryogenic measurements and available for convenient and reliable strain tuning.
Download or read book Magnetism in Condensed Matter written by Stephen Blundell and published by OUP Oxford. This book was released on 2001-10-05 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: An understanding of the quantum mechanical nature of magnetism has led to the development of new magnetic materials which are used as permanent magnets, sensors, and information storage. Behind these practical applications lie a range of fundamental ideas, including symmetry breaking, order parameters, excitations, frustration, and reduced dimensionality. This superb new textbook presents a logical account of these ideas, staring from basic concepts in electromagnetsim and quantum mechanics. It outlines the origin of magnetic moments in atoms and how these moments can be affected by their local environment inside a crystal. The different types of interactions which can be present between magnetic moments are described. The final chapters of the book are devoted to the magnetic properties of metals, and to the complex behaviour which can occur when competing magnetic interactions are present and/or the system has a reduced dimensionality. Throughout the text, the theorectical principles are applied to real systems. There is substantial discussion of experimental techniques and current reserach topics. The book is copiously illustrated and contains detailed appendices which cover the fundamental principles.
