Magnetic Evaluation of Ni-Zn Ferrites Doped with Aluminium

Abstract:

Ni_0.5Zn_0.5Fe_1.97Al_0.3O₄ ferrites were synthesized by combustion reaction method and after calcined at 700°C/1 h, with the aim to investigate how the Al³⁺ ions substitution byNi²⁺ ions can influence the magnetic properties. The results from X-ray diffraction showed the formation of a unique Ni-Zn ferrite phase with average crystallite size of 8 and 22nm, before and after calcination, respectively. The synthesize samples presented a superparamagnetic behavior, with saturation magnetization of 0.9 emu/g, and coercive field of 0.05 kOe, and after calcination the samples presented soft magnetic behavior with saturation magnetization of 40.0 emu/g and coercive field of 0.04 kOe.
