【 摘 要 】

Li0.4-0.5xZn0.2NixFe2.4-0.5xO4ferrites where 0.02 ≤ x ≤ 0.1 in steps of 0.02 have been synthesized by citrate precursor method. The samples were given final sintering at 1040°C after a pre-firing at a temperature of 650°C. Various characterizations using TCset up, BH loop tracer were carried out on the sintered samples. The X-ray diffraction pattern confirmed the formation of spinel phase. Magnetic properties such as Curie temperature using TCset up, BH loop parameter and complex permeability using BH loop tracer were studied. Experimental results show that the Curie temperature, saturation magnetization and initial permeability decreases with the increase in the Ni2+concentration. The complex permeability measured as a function of frequency in the range of 20Hz-2MHz show dispersion. Possible mechanism contributing to the above process is being discussed.
