Terbium doped Ni-Cd mixed ferrite samples with general formula Ni_(0.9)Cd_(0.1)Tb_xFe_(2-x)O_4 (x = 0, 0.02, 0.06 and 0.1) were prepared through sol-gel technique. The effect of terbium doping on the properties of Ni-Cd ferrite has been investigated using different characterization techniques like X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), Wavelength Dispersive X-Ray Fluorescence Spectrometer (WD-XRF), Transmission Electron Microscope (TEM) and Vibrating Sample Magnetometer (VSM). XRD analysis confirmed the formation of single phase spinel structure in all the samples. Tb~(3+) doping has resulted in increased saturation magnetization and enhanced resistivity of Ni-Cd mixed ferrite.
