Abstract: Ni0.65Zn0.35Fe2O4 nanoparticles synthesized by sol-gel process have been subjected to various annealing temperatures with a view of obtaining size dependent properties and critical length. X-ray diffraction, transmission electron microscopy, VSM and ESR experiments were carried out as a function of crystallite size. From the ESR spectra it has been observed that the sample annealed at 1025°C has least magnetic anisotropy. The observed variations in saturation magnetization and coercive field have been explained in terms of magnetic anisotropy.
