Abstract

In this investigation nickel-cadmium Ferrite Nanoparticle with stoichiometric composition of Ni0. 3Cd0. 7Fe2O4 was synthesized by Sol-gel auto-combustion method. In order to study the effect of particle size on physical properties of samples, the powder samples was annealed at temperatures 350, 400, 450 and 500 ○ C for 3h. Structural, morphological and magnetic properties of samples were analyzed using X-ray diffraction (XRD), field emission scanning electron microscope (FESEM), vibrating sample magnetometer (VSM) and ac susceptibility. XRD data revealed spinel mono-phase formation and crystallite size was estimated in the range of 17-35 nm, using sherrer’ s equation which also confirmed by FESEM. The VSM results indicate that magnetization increases by increasing particle size. Using the results of ac susceptibility measurements and analysis by the Neel-Brown, Vogel-Fulcher and critical slowing down methods, indicates that the samples annealed at temperatures of 350 and 400 ○ C are super-paramagnet at room temperature and have Super-spin glass behavior at low temperatures.
