Magnetic Properties of Ni-Zn Ferrites by Citrate Gel Method

Abstract

Ni-Zn ferrite with a nominal composition of Ni 1−x Zn x Fe 2 O 4 (x = 0, 0.2, 0.6, 0.8, 0.9) are prepared by citrate gel method and characterized by X-ray diffraction. Magnetic properties of all samples are obtained by using VSM (Vibrating Sam-ple Magnetometer) in the range of 10 Koe. The saturation magnetization values of the samples are carried out from the B-H loop. The effect of composition on saturation magnetization and magnetic moment are studied in this paper. The results showed that Saturation magnetization and magnetic moment values increases gradually as Zn 2+ composition in-creases, it reaches maximum value 70.28 emu/gm for (x = 0.6) and decreases further with increasing Zn 2+ composition.
