| Abstract: | Ni-Zn ferrites with NixZn1-xFe2O4(with x=0.2,0.4,0.6,0.8) were prepared by the powder metallurgy sintering method.Ni-Zn ferrites powder were characterized by X-ray powder diffraction(XRD),scanning electron microscopy(SEM),and vibrating sample magnetometer(VSM).Magnetic properties of Ni-Zn ferrites circular magnetic core were studied by MATS-2000 automatic magnetism measuring instrument.It was found that the saturation magnetization of NixZn1-xFe2O4 powder increased firstly and decreased afterwards with the ... |
