Unparalleled in the breadth and depth of its coverage of all important aspects, this book systematically treats the electronic and magnetic

properties of stoichiometric and non–stoichiometric cobaltites in both ordered and disordered phases. Authored by a pioneer and a rising star

in the field, the monograph summarizes, organizes and streamlines the otherwise difficult–to–obtain information on this topic. An introductory

chapter sets forth the crystal chemistry of cobalt oxides to lay the groundwork for an understanding of the complex phenomena observed

in this materials class. Special emphasis is placed on a comprehensive discussion of cobaltite physical properties in different structural families.

Providing a thorough introduction to cobalt oxides from a chemical and physical viewpoint as a basis for understanding their intricacies,

this is a must–have for both experienced researchers as well as entrants to the field.
