Abstract: Work presented in this thesis describes studies on structural, magnetic and Mössbauer spectroscopy characterization on nano and bulk samples of pure nickel-zinc ferrite having basic composition Ni0.58Zn0.42Fe2O4 and indium doped nickel-zinc ferrite (Ni0.58Zn0.42InxFe2-xO4, x = 0.1, 0.2, 0.3) samples. Nano ferrite particles have been prepared by reverse micelle technique. Bulk samples in this study are prepared by annealing the reverse micelle synthesized nanoparticles at high temperature 1473 K. Prepared bulk and different size nanoparticles have been characterized using X-ray diffraction (XRD), transmission electron microscopy (TEM) and Fourier transform infrared spectroscopy (FTIR) studies. 57Fe Mössbauer measurements have been made in the temperature range from 5-300 K for determining the cation redistribution and hyperfine parameters. For studying the magnetic behavior dc magnetization have been performed using vibrating sample magnetometer and SQUID magnetometer, whereas to study the dynamic behavior ac susceptibility measurements have been performed. newline newline
