Abstract
A series of CdxCo1-xCr0.5Fe1.5O4 ferrite sample with (x = 0, 0.2, 0.4, 0.6, 0.8, 1.0) have been prepared by powder metallurgy method. The structural, morphological, magnetic and optical properties of prepared samples have been characterized by X-ray diffractometer (XRD), Fourier transform infrared spectroscopy (FTIR), Scanning electron microscope (SEM), Vibrating sample magnetometer (VSM) and UV–visible spectroscopy respectively. The distribution of cation in site-A, site-B and lattice parameters have been deduced by X-ray-diffraction-data analysis. The lattice constant (A°) was found to increase with increment of Cd2+ contents in the spinel ferrites. The hysteresis curves undoubtedly designate the soft nature of the prepared ferrite samples. The saturation magnetization (Ms) decreases with increasing Cd contents3w, this result is interrelated to the magnetic moments of Cd2+ ions. The Y–K angles decrease with addition of cadmium content and this decrement in the Y–K angles proposes the lessening of triangular spin arrangements on octahedral sites which consequently lead to decrease the A-B interaction. The band gap energy is showing the increasing trend which is due to decreasing crystallite size.
