Electromagnetic Properties (Mxzn1â??X) Fe2o4 (M=Cd, Ni) Ferrites Nano Particles

The Present invegestion the chemical co-precipitation method was used to prepare a nano scale ferrite powder with Cd-Zn and Ni-Zn compositions. Ferrite, in different Cd-Zn stoichiometric ratios, showed optimal composition of saturated magnetization for Cd0.7Zn0.3Fe2O4; under an air environment and claimed at 700C, the saturated magnetization was 60.19 M(emu/g). The average particle diameter was 12 nm for the non-claimed sample, while when the sintering temperature was 800 C, the particle diameter was about 120 nm. In addition, in different Ni-Zn stoichiometric ratios, the optimal composition of the saturated magnetization was Ni0.5 Zn0.5Fe2O4; under an air environment and calcinations at 700?C the saturated magnetization was 91.40 M(emu/g). The average particle diameter for the non-claimed sample was about 12 nm, but when the sintering temperature was 700 ?C, the particle die diameter was 201.06 nm. The prepared ferrite nano-powder was characterized by scanning electron microscopy(SEM), X-ray diffraction(XRD), and vibrating sample magnetometer(VSM) to reveal its microscopic structure and related electromagnetic properties. Ferrite powders of either Cd-Zn or Ni-Zn composition can be used as catalysts for chemical reactions or iron core materials.
