AN APPROACH TO DEVELOP SUITABLE COMPOSITION OF Mg-Mn FERRITE WITH HIGH VALENCE CATIONS

摘要

Density, microstructure, resistivity, magnetic properties and hysteresis loop parameters studies have been carried out by substitution of high valence cations such as Ti~(4+), Zr~(4+), Sb~(5+) and Mo~(6+) in Mg-Mn ferrite to develop suitable and good composition. The obtained experimental results have been discussed based on the possible theoretical proposals. Mg-Mn ferrite with 0.1 concentration of Mo~(6+) found to is good by improving majority properties namely grain size, resistivity, Ms, permeability with not much deterioration of other physical parameters.
