Extensive studies of high-Tc cuprate superconductors have stimualted investigations into various transition-metal oxides. Mott transitions in particular provide fascinating problems and new concepts in condensed matter physics. This book is a collection of overviews by well-known, active researchers in this field. It deals with the latest developments, with particular emphasis on the theoretical, spectroscopic, and transport aspects.

Yoshinori Tokura is Professor of Applied Physics at the University of Tokyo since 1994. Since 2007, he is also Group Director of RIKEN Advanced Science Institute. He has been investigating transition-metal oxide materials that exhibit strong electron correlation. With his research on giant magnetoelectric responses from multiferroics he extraordinarily contributed to the present knowledge on this topic. Professor Tokura was multiply awarded for his research achievements, among others with the Nishina Memorial Prize, Matthias Prize, Asahi Prize, MacGroddy Prize, and Fujihara Prize for correlated electron research.
