The field of nano-crystalline and thin film magnetic oxides is truly multidisciplinary. The present book provides the necessary broad view, giving the reader a better understanding of the problems involved. The book deals with the three main areas in the study of magnetic oxides for microwave and magnetooptical applications: thin films and nano-crystalline ferroxides; magnetic behaviour and applications of oxides with perovskite structures; and nano-sized materials and modelling. The development of planar devices for high-density magnetic and magnetooptical recording and microwave integral technologies has led to a substantial growth of scientific interest in nano-crystalline and thin film magnetic oxides, such as ferrites, manganates and cuprates. Readership: Teachers, researchers, academic and industrial level workers concerned with magnetic oxides.
