Magnetic Properties of Cu1-xZnxFe2 O4Ferrites with the Variation of Zinc Concen-tration


Cu-Zn ferrite with general formula of Cu1-xZnxFe2 O4 with a range from x = 0.0 to 0.7 (in steps of 0.1) was prepared by using standard ceramic techniques. The confirmation of sin-gle-phase formation was carried out by employing X-ray diffraction technique. Some of the magnetic properties were measured, such as Curie temperature, the complex permeability and low field hysteresis loop. It was found that Curie temperature Tc decreases from 464?C to 20?C. The real part of initial permeability, μ in-crease with increasing Zn contents up to x = 0.5 after that it decreases with higher Zn content. Low field hysteresis measurement was carried out at room temperature and this measurement with the increase of Zn2+ ions yields the increase of saturation magnetic induction (By) and magnetic remanance (Br) up to x = 0.4 thereafter it decreases. The decrease in corecivity (Hc) and hysteresis loss is observed for all samples. In view of this, the possible changes in magnetic properties with the increase in Zn concentration are un-dertaken.
