Applied Thermal Physics Laboratory, Department of Physics, COMSATS Institute of Information Technology, 44000, Islamabad, Pakistan aut Synthesis and Thermophysical Studies of Nanoferrites [Elektronische Daten] [M. Anis-ur-Rehman] Soft ferrites are very useful for a wide variety of technological applications especially in high frequency devices due to high resistivity and low eddy current losses. Co nanoferrite particles were synthesized by co-precipitation method and characterized to understand the microstructure and electrical transport properties. The composition was varied by changing the "A” concentration in Co1−x A xFe2O4 (A= Zn, Ni) nanoparticles with stoichiometric proportion (x) varying from 0.0 to 1.0. X-ray diffraction was used for structural analysis. Then samples were sintered at 550 °C and 750 °C for 2 hours, characterized by X-ray diffraction at room temperature and DC electrical resistivity measurements were done as a function of temperature. The effects of sintering on structure were investigated. Activation energy was calculated from DC electrical resistivity data as a function of temperature.
