摘要：

We discuss the possible mechanisms responsible for ferromagnetic ordering in transition metal oxides and the interplay between electrical transport and magnetic order. We emphasize the role of orbital degrees of freedom, electron correlation effects, local lattice distortions and the oxygen 2p bands in high oxidation state TM oxides. For illustration of the physics we discuss several specific materials like Eu chalcogenides, magnetic semiconductors, La manganates and CrO2 among others. (C) 1997 Elsevier Science Ltd.
