Abstract

The chemical composition and preparation methods for ferrite were studied in order to control the quality of ferrite such as higher initial permeability and low energy losses. Nine samples of soft ferrite MxZn 1-xFe2O4 with M=Ni, Mg, Cu ; x=0.2, 0.3, and 0.4 was prepared using solid state ceramic method and characterized for initial permeability, coercivity and relative loss factor (RLF). Studies show that samples with low Zn concentration, x=0.4, exhibit higher initial permeability, μi, with magnitude highest in sample with Ni concentration, that also has the highest atomic susceptibility among Ni, Mg and Cu. Initial permeability, μi ,also influences the resistivity of the samples with increasing susceptibility of magnetic spins, so samples with higher μi, e.g. Ni0.4Zn0.6Fe2O4 exhibit increased resistivity with increased initial permeability while Cu0.4Zn 0.6Fe2O4 exhibit decreasing resistivity with increasing Cu content and lower initial permeability.
