Book Description
This series of books, which is published at the rate of about one per year, addresses fundamental problems in materials science. The contents cover a broad range of topics from small clusters of atoms to engineering materials and involves chemistry, physics, materials science and engineering, with length scales ranging from Ångstroms up to millimeters. The emphasis is on basic science rather than on applications. Each book focuses on a single area of current interest and brings together leading experts to give an up to date discussion of their work and the work of others. Each article contains enough references that the interested reader can access the relevant literature. Thanks are given to the Center for Fundamental Materials Research at Michigan State University for supporting this series. M. F. Thorpe, Series Editor E mail: thorpe@pa. msu. edu V PREFACE This book records invited lectures given at the workshop on Physics of Manganites, held at Michigan State University, July 26 29, 1998. Doped manganites are an interesting class of compounds that show both metal insulator and ferromagnetic to paramagnetic transitions at the same temperature. This was discovered in the early 1950s by Jonker and van Santen and basic theoretical ideas were developed by Zener (1951), Anderson and Hasegawa (1955), and deGennes (1960) to explain these transitions and related interesting observations.

Book Description
The study of the spontaneous formation of nanostructures in single crystals of several compounds is now a major area of research in strongly correlated electrons. These structures appear to originate in the competition of phases. The book addresses nanoscale phase separation, focusing on the manganese oxides known as manganites that have the colossal magnetoresistance (CMR) effect of potential relevance for device applications. It is argued that the nanostructures are at the heart of the CMR phenomenon. The book contains updated information on manganite research directed to experts, both theorists and experimentalists. However, graduate students or postdocs will find considerable introductory material, including elements of computational physics.

Book Description
The physics of transition metal oxides has become a central topic of interest to condensed-matter scientists ever since high temperature superconductivity was discovered in hole-doped cuprates with perovskite-like structures. Although the renewed interest in hole-doped perovskite manganites following the discovery of their colossal magnetoresistance (CMR) properties, began in 1993 about a decade after the discovery of high temperature superconductivity, their first investigation started as early as 1950 and basic theoretical ideas were developed during 1951-1960. Experience in sample preparation and characterization, and in growth of single crystals and epitaxial thin films, gained during the research on high temperature superconductors, and the development of theoretical tools, were very efficiently used in research on CMR manganites. In early nineties it appeared to many condensed matter physicists that although the problem of high temperature superconductivity is a difficult one to solve, a quantitative understanding of CMR phenomena might be well within reach. This book is intended to be an account of the latest developments in the phys ics of CMR manganites. When I planned this book back in 2000, I thought that research on the physics of CMR manganites would be more or less consolidated by the time this would be published. I was obviously very optimistic indeed. We are now in 2003 and we still do not have a quantitative understanding of the central CMR effect. Meanwhile the field has expanded. It is still a very active field of research on both the experimental and theoretical fronts.

Book Description
Metal oxides constitute one of the most amazing classes of materials with a wide range of properties. They exhibit a variety of phenomena, such as ferroelectricity, ferromagnetism and superconductivity. A new aspect of metal oxides -- colossal magnetoresistance exhibited by certain manganese oxides, in particular rare earth manganates of perovskite structure -- has received much attention in the last four years. Some of these oxides show 100% magnetoresistance and have much potential for technological applications. Previously this phenomenon was found only in layered and granular metallic materials. Studies of colossal magnetoresistance have led to the discovery of many other new phenomena and properties such as charge ordering and orbital ordering. In view of the importance of colossal magnetoresistance, charge ordering and related phenomena exhibited by oxides to the physics and chemistry of solid materials, it is necessary and timely to have a book dealing with these topics. This book begins with a review of the subject followed by contributions from a number of experts which cover the present status of the subject.

Book Description
The book is focused on the nanoparticle-based modification of micron-size ZnO, TiO2, ZrO2, Al2O3, CeO2, and Y2O3 oxide powders and BaSO4, BaTiZrO3, and LaSrMnO3 solid solutions applied for enamels, paints, construction materials, ceramics, and electric insulators. It presents the results of studies of the grain size distribution, phase composition, structure, optical properties, and physical processes that occur in micropowders modified with ZnO, TiO2, ZrO2, Al2O3, CeO2, Y2O3, SiO2, ZrO2/Y2O3, and Al2O3/CeO2 nanoparticles and subsequently irradiated with accelerated electrons and protons. The text will be helpful to researchers, engineers, structural developers, postgraduates, master’s students, and undergraduate students who study the processes that occur during the synthesis and modification of inorganic powders with nanoparticles of various oxides differing in the size and type of cations, in their mass and charge, and in the size and surface area of nanoparticles per se.

Book Description
A one-of-a-kind text offering an introduction to the use of spectroscopic ellipsometry for novel material characterization In Introduction to Spectroscopic Ellipsometry of Thin Film Materials: Instrumentation, Data Analysis and Applications, a team of eminent researchers delivers an incisive exploration of how the traditional experimental technique of spectroscopic ellipsometry is used to characterize the intrinsic properties of novel materials. The book focuses on the scientifically and technologically important two-dimensional transition metal dichalcogenides (2D-TMDs), magnetic oxides like manganite materials, and unconventional superconductors, including copper oxide systems. The distinguished authors discuss the characterization of properties, like electronic structures, interfacial properties, and the consequent quasiparticle dynamics in novel quantum materials. Along with illustrative and specific case studies on how spectroscopic ellipsometry is used to study the optical and quasiparticle properties of novel systems, the book includes: Thorough introductions to the basic principles of spectroscopic ellipsometry and strongly correlated systems, including copper oxides and manganites Comprehensive explorations of two-dimensional transition metal dichalcogenides Practical discussions of single layer graphene systems and nickelate systems In-depth examinations of potential future developments and applications of spectroscopic ellipsometry Perfect for master’s- and PhD-level students in physics and chemistry, Introduction to Spectroscopic Ellipsometry of Thin Film Materials will also earn a place in the libraries of those studying materials science seeking a one-stop reference for the applications of spectroscopic ellipsometry to novel developed materials.
