Structural and Magnetic Properties of Mn<sub>0.50-x</sub>Zn<sub>0.50</sub>Cu<sub>x</sub>Fe<sub>2</sub>O<sub>4</sub>

Abstract

ABSTRACTcontent. It is observed that both density and initial permeability increase with increasing sintering temperature. The maximum initial permeability is found to be 1061 which is almost four times greater than that of the parent composition. The resonance frequency of all the samples shifts towards the lower frequency as the permeability increases with Cu 2+ content. It is observed from B-H loops of Mn 0.50-x Zn 0.50 Cu x Fe 2 O 4 that coercivity decreases and retentivity increases with Cu 2+ content. Possible explanations for the observed magnetic properties with various Cu 2+ contents are discussed.
