Abstract

Abstract Sol-gel auto-combustion synthesized Ni0.5Co0.5FeCrO4 ferrite nanoparticles were sintered at four different temperatures. As depicted by thermo-gravimetric analysis the major weight loss is occurred between the temperatures 5000C to 6000. The X-ray diffraction peaks observed are identified by the crystal planes (220), (311), (222), (400), (422), (333), (440), (533) which belongs to cubic spinel structure with space group Fd3m. The other structural parameters like lattice constant, X-ray density, porosity and crystallite size were calculated by using XRD data. The sufficiently broadening of the peaks confirms the nanometer size of the synthesized powders. With increasing the sintering temperature the broadening slightly reduces which increases the size of the crystallite. The surface morphology and average grain size was studied by using SEM images. The magnetic properties such as saturation magnetization, coercivity, remnant magnetization were studied by using room temperature VSM technique. Increasing sintering temperature increases the saturation magnetization and coercivity.

Key Words

Keywords: Crystallite size, sintering temperature, saturation magnetization.
