This book was released on 1998-12-24 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interplay of magnetism and electronic correlations dominates the physical properties of many rare-earth elements and their compounds. The investigation of the mutual influence of the localized 4f electrons and itinerant band electrons represents a challenging task in theoretical as well as experimental physics. Research areas of current interest are the electronic structure as determined from calculations and spectroscopies, the magnetic properties in three- and low-dimensional systems, open questions concerning transport such as spin disorder resistivity, and the influence of structure and morphology.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive overview of the fascinating recent developments in atomic- and nanoscale magnetism, including the physics of individual magnetic adatoms and single spins, the synthesis of molecular magnets for spintronic applications, and the magnetic properties of small clusters as well as non-collinear spin textures, such as spin spirals and magnetic skyrmions in ultrathin films and nanostructures. Starting from the level of atomic-scale magnetic interactions, the book addresses the emergence of many-body states in quantum magnetism and complex spin states resulting from the competition of such interactions, both experimentally and theoretically. It also introduces novel microscopic and spectroscopic techniques to reveal the exciting physics of magnetic adatom arrays and nanostructures at ultimate spatial and temporal resolution and demonstrates their applications using various insightful examples. The book is intended for researchers and graduate students interested in recent developments of one of the most fascinating fields of condensed matter physics.

Available in PDF, EPUB and Kindle. Book excerpt: Volume 13 of the Handbook of Magnetic Materials, as the preceding volumes, has a dual purpose. As a textbook it is intended to be of assistance to those who wish to be introduced to a given topic in the field of magnetism without the need to read the vast amount of literature published. As a work of reference it is intended for scientists active in magnetism research. To this dual purpose, Volume 13 of the Handbook is composed of topical review articles written by leading authorities. In each of these articles an extensive description is given in graphical as well as in tabular form, much emphasis being placed on the discussion of the experimental material in the framework of physics, chemistry and material science. In Chapter 1 of this volume a general review of the experimental work on interlayer exchange coupling is presented along with a discussion of the current understanding of this field. There exists an extensive amount of scientific efforts devoted to 4f and 5f systems, including experimental and theoretical, as well as basic and applied research. Chapter 2 aims at reviewing a part of these efforts from the viewpoint of microscopic theory. Special attention is paid to the many new developments in the field. One of the intentions is to bring to the fore the darker areas of DFT theory applications. A review of novel experimental results and first-principle energy-band calculations of MOKE spectra will be presented in Chapter 3. Conventional co-operative phenomena, such as long-range order and elementary excitation, have realisations in nonmagnetic situations. This applies also to the phenomena of geometrical frustration. In Chapter 4 this topic is addressed by developing the basic principles underlying the magnetic phenomena.

Download or read book Strong Coulomb Correlations in Electronic Structure Calculations written by Vladimir I Anisimov and published by CRC Press. This book was released on 2000-05-30 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: Materials where electrons show nearly localized rather than itinerant behaviour, such as the high-temperature superconducting copper oxides, or manganate oxides, are attracting interest due to their physical properties and potential applications. For these materials, the interaction between electrons, or electron correlation, plays an important role in describing their electronic strucuture, and the standard methods for the calculation of their electronic spectra based on the local density approximation (LDA) breakdown. This is the first attempt to describe recent approaches that go beyond the concept of the LDA, to successfully describe the electronic structure of narrow-band materials.

Download or read book Field induced Magnetic Phase Transitions and Correlated Electronic States in the Hexagonal RAgGe and RPtIn Series written by Emilia Morosan and published by . This book was released on 2005 with total page 538 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rare earth intermetallic compounds provide rich grounds for investigating the properties of both local moment and strongly correlated, hybridized moment systems. These areas have been intensively explored mostly on cubic and tetragonal intermetallic compounds, and very little work existed on materials with lower symmetry. Moreover, a large number of Ce-based heavy fermion compounds have been studied, whereas the analogous Yb-based ones are much rarer. We thus wanted to study local moment metamagnetism and Yb-based heavy fermion physics in hexagonal systems. The RAgGe and RPtln series belonging to the Fe2P family of hexagonal compounds allowed us to perform such studies on both local moment and strongly correlated, hybridized moment systems. The RAgGe and RPtln compounds presented in this work display anisotropic temperature and field dependent magnetization due to the crystalline electric field (CEF) splitting of the Hund's rule ground state multiplet. The TmAgGe and TbPtln members of these series display extreme planar anisotropy, which makes them well suited for a study of the angular dependent metamagnetism. We developed the three co-planar Ising-like systems model, which allowed us to determine the net distribution of the magnetic moments in the two compounds. The YbAgGe and YbPtln compounds have some properties distinct from the rest of their respective series: having low ordering temperatures and enhanced electronic specific heat coefficient [Gamma], they can be classified as stoichiometric, Yb-based heavy fermion compounds, with a magnetic field-induced quantum critical point QCP. In the former compound, a non-Fermi liquid-like NFL regime is apparent at intermediate fields, but such a behavior is more ambiguous in the YbPtln. However, a small Pt-deficiency in flux-grown YbPt0.9ln single crystals seems to stabilize, together with the magnetic field, a non-Fermi liquid-like NFL regime. In summary, TmAgGe and TbPtln are hexagonal compounds revealing complex, and yet intelligible angular dependent metamagnetism; together with the quantum critical physics found in YbAgGe and YbPtln, the RAgGe and RPtln series dramatically confirm the fertile grounds for research that can be found in these hexagonal systems.

Book excerpt: It is well known that rare earth intermetallic compounds have versatile, magnetic properties associated with the 4f electrons: a local moment associated with the Hund's rule ground state is formed in general, but a strongly correlated, hybridized state may also appear for specific 4f electronic configuration (eg. for rare earth elements such as Ce or Yb). On the other hand, the conduction electrons in rare earth intermetallic compounds, certainly ones associated with non hybridizing rare earths, usually manifest non-magnetic behavior and can be treated as a normal, non-interacted Fermi liquid, except for some 3d-transition metal rich binary or ternary systems which often manifest strong, itinerant, d electron dominant magnetic behavior. Of particular interest are examples in which the band filling of the conduction electrons puts the system in the vicinity of a Stoner transition: such systems, characterized as nearly or weakly ferromagnet, manifest strongly correlated electronic properties [Moriya, 1985]. For rare earth intermetallic compounds, such systems provide an additional versatility and allow for the study of the behaviors of local moments and hybridized moments which are associated with 4f electron in a correlated conduction electron background.
