Enhanced descriptions from Syndetics:

Transition metal oxides form a series of compounds with a uniquely wide range of electronic properties. They have important applications as dielectrics, semiconductors, and metals, and as materials for magnetic and optical uses. The recent discovery of high-temperature superconductors has brought the attention of a wide scientific community to this area, and has highlighted the problems involved in trying to understand transition metal oxides. The present book is not primarily about high Tc superconductors, although their properties are discussed in the final section. The main aim is to describe the varied electronic behavior shown by transition metal oxides, and to discuss the different types of theoretical models that have been proposed to interpret it. It is intended to provide an introduction to this fascinating and complex field, at a level suitable for graduate students and other research workers with a background in solid-state chemistry or physics.

CHOICE Review

Many aspects of the properties of transition metal oxides are covered by Cox, who claims that his purpose is to survey the electronic properties of these oxides which include magnetic, optical, and spectroscopic properties, and to discuss models to interpret them. An introductory chapter treats the chemical aspects of transition metals such as oxidation states, stability, structural geometries, and defects in geometry, and a second chapter deals with the models of electronic structure. Here, the main topics are crystal field theory, cluster models, band theory, and various other models such as Hubbard potentials, excitons, and polarons. This reviewer, familiar with crystal field theory, is of the opinion that Cox's overview here requires prior knowledge of the theory. There is ample coverage of band theory. The last three chapters deal with major topics: insulating, defect, magnetic, and superconductive properties. Throughout, there are many equations and graphical representations but a lack of experimental and mathematical details. The book is meant to be a survey of the field and the reader must rely on the references to find the details. Graduate; researcher. W. H. Hohman; Marietta College
