Magnetic Perovskites

Magnetic perovskite with multifunctional properties (magneto-resistive,§magneto-dielectric, multiferroics, spintronics, etc.) have attracted increasing§attention due to their possible applications towards storage materials and§intriguing fundamental Physics. Despite the numerous investigations on§multifunctional materials in the past few years, a very few magnetic§perovskites have been known to realize as ferromagnetic-insulators. In perovskites§centred transition metal oxides strong interplay between lattice, charge, spin§and/or orbital degrees of freedom provide a fantastic playground to tune their§physical properties. The main purpose of this book is to introduce the§phenomenon and physics of complex magnetism (phase separation, spin glass,§frustrations, etc.) in perovskite manganites and cobaltites via an experimental§approach. The book is organized into four sections; Section A gives a brief§introduction of various interesting phenomena in magnetic perovskites. Section§B describes the results of the investigations on electronic phase separation§and glassy ferromagnetism of the hole-doped perovskite manganites and§cobaltites. Ordered and disordered effects and related aspects in hole-doped perovskite§cobaltites are described in Section C. Finally, in Section D the bismuth based§magnetic perovskite is discussed.§§
