Abstract

The Li-Mn ferrites with composite divalent and tetravalent non-magnetic ions doping were prepared by ceramic method and studied for the first time to investigate their structural and electrical properties. It has been confirmed from the studies that these materials result in properties suitable for microwave applications. The structural properties have con- firmed the formation of cubic spinel ferrite and the substitutions of non magnetic ions have resulted in increase of unit cell dimensions and hence the grain size with increase in dopant content. An IR study asserts the same. Electrical Prop- erties show increase in dc resistivity and decrease in dielectric loss tangent with increase in dopant concentration.
