Magnetic Properties Analysis of Rare-Earth Substituted Nickel Zinc Ferrites

The raw compounds with the chemical composition Ni<sub>0.42</sub>Zn<sub>0.58</sub>Me<sub>x</sub>Fe<sub>2-x</sub>O<sub>4</sub> where Me = Eu, Gd, La (x = 0, 0.01, 0.02, 0.04, 0.06) were synthesized by means of the ceramic technique. The magnetic properties and magneto-chemical composition and structure of various doped nickel zinc ferrites were estimated by X-ray spectroscopy, EDAX analysis, and study of the behavior of susceptibility with changing temperature, complex permeability spectra, and magnetic hysteresis loop measurement.
