| Popis: | This article reports synthesis, electrical, and magnetic properties of Ni0.5-xCdxZn0.5Fe2O4 (with X = 0.0, 0.15, 0.30, and 0.45) ceramics by simple solid state method. The temperature dependence of the electrical conductivity plot shows the semiconducting behavior, which can be attributed to ferromagnetic-paramagnetic transition. The activation energies obtained from resistivity plots in paramagnetic region is witnessed to be more than that in ferri-magnetic region. The conduction mechanism in nickel-zinc (Ni-Zn) ferrite particles has been discussed on the basis of hopping of electrons. The magnetic hysteresis at room temperature indicates the ferri-magnetic behavior of synthesized ferrite system. The detailed influence of cadmium doping in Ni-Zn ferrites found to be enhances saturation magnetization, remnant magnetization, coercivity, magnetic moment, and Y-K angles. |
