About The Book

Finely tuned electrical and magnetic properties are the goal of all materials scientists. More energy efficient electronic devices, better performing hybrid electrical vehicles and smarter data storage devices are among potential applications for suitable material. Spinel ferrites possess the crystal structure of the natural spinel MgAl2O4. This structure is particularly stable, since there is an extremely large variety of oxide which adopt in fulfilling the conditions of overall cation to anion ratio of 3/4. Mixed magnetic oxides have fascinating properties with coexistence of ferrous and ferric cations in coordination with various cation combinations through stochiometric. The spnel structure is able to form an extremely wide variety of total solid solutions. It means the composition of a given ferrite can be strongly modified, while the basic crystalline structure remains the same. Present book introduces the method and techniques for synthesis and characterization of mixed magnetic oxides having spinel structure. Mixed magnetic oxides are basically spinel ferrites having specific stoichiometry and compositions of different cations, which is stable and has extremely large potential of variety of oxides depending on cations and cation distributions among octahedral and tetrahedral sites. The book presents study of two solid solutions, Ni0.7Mg0.3AlxFe2-xO4 and Ni0.7Mg0.3CrxFe2-xO4.

The book has four chapters. First chapter introduces the basic structure and compositions sensitive properties of mixed magnetic oxides having spinel structure along with background of development in study of spinel ferrites. The second chapter presents information about spinel structure and ferrimagnetism. The third chapter is regarding experimental techniques and characterization of the mixed magnetic oxides. The last and fourth chapter gives systematic analysis of material properties achieved by the solid solutions under investigation. Thus the book is intended to introduce the most fundamental things required for the synthesis and characterization for solid solutions of mixed magnetic oxides in order to develop research interest. Hope the book will be useful for beginners, students, teachers and researchers.
