Abstract :
In this paper, Ni/sub x/Mn/sub 0.4-x/Zn/sub 0.6/Fe/sub 2/O/sub 4/, with different compositions are synthesized by the citrate precursor method and their dc resistivity, dielectric relaxation intensity, complex initial permeability, Curie temperature, saturation magnetization and the B-H loop parameters have been studied. X-ray diffractions of all samples (calcined at 500/spl deg/C) show single-phase spinel structure.
