Magnetic and dielectric properties of ba based m and y type hexaferrites

Abstract

Hexaferrites are one of the important class of materials in the family of permanent magnets due to their potential applications in various electronic and microwave devices Based on chemical formula and crystal structure hexaferrites are classified into six types such as M Y Z W X and U The present thesis describes the structural dielectric and magnetic properties of Ni Ti Al substituted M type hexaferrites and Zn and Mg substituted Y type hexaferrites M type hexaferrite with composit...
