This book is a comprehensive account of the present understanding of an important class of perovskite oxide materials with potential industrial applications. The chapters are written by well-known scientists who are on the forefront of the field and have directly contributed to its recent progress. Special care has been taken to maintain a balance between the space devoted to new experimental results and that devoted to recent theoretical developments. The book contains recent experimental and theoretical results on colossal magnetoresistive (CMR) manganites not covered by any other book in the field, and hence this will be very beneficial to graduate students and researchers in condensed matter and applied physics, materials science and solid state chemistry
