Abstract

Nanosized Mn_0.5Ni_0.5Fe_2-xPr_xO₄, x=0.0, 0.02, 0.04, 0.06, 0.08, 0.1 and 0.15 are prepared by co-precipitation method at calcination temperature 650^oC for 4 hours. X-ray diffraction patterns show the presence of the cubic (Mn-Ni)- ferrite phase and anti-ferromagnetic a-Fe₂O₃. The variation in the lattice parameter “a” is due to the replacement of smaller radius ions Fe⁺³ by larger radius ions Pr⁺³. Transmission electron micrographs indicate that the particles are spherical in shape. The moderately agglomerated particles are present due to the interaction between the magnetic nanoparticles. UV-visible optical (UV) and Fourier Transform Infrared (FTIR) spectroscopies show a significant change in the absorption bands as the Pr content increases. The calculated values of the optical band gap energies show an increase as the Pr content increases. This is due to the decrease of the particle size. From VSM analysis, it was found that the saturation magnetization (M_s) and the coercivity (H_c) are strongly dependent on Pr content. The results of M-H loop are interpreted in terms of the observed anti-ferromagnetic phase a-Fe₂O₃, phase core shell interaction and cation redistribution.
