Abstract Cadmium substituted Nickel Ferrite, Ni0.5CoxCd(0.5-x)Fe2O4 (x = 0.0, 0. 02) were synthesized by sol-gel auto-combustion technique with microwaves using urea as fuel. The samples were sintered at two different temperatures 600 °C and 800 °C. This paper discusses the effect of sintering temperature on varius structural, morpological, magnetic and optical properties of the syntesized samples. The structural properties such as crystallite size, lattice constant, lattice strain oxygen position parameters, bond lengths and bond angles. Phase analysis of the sample are carried out using XRD measurement. Surface morphology and qualitative and quantitative chemical composition of the samples were done by FE-SEM and energy dispersive X-ray analysis (EDX) measurements respectively. Magnetic properties such as saturation magnetization (Ms), coercivity () retentivity (Mr), squareness and were obtained from VSM measuements. The variation in the observed and measured magnetic quantities are explained on the basis of YK model.The cation distribution proposed has been discussed based on the observed experimental measured magnetic parameters and it futher discuss spin canting angle and nature of exchange interaction among the magnetic moments of octahedral and tetrahedral sites.
