Magnetic nanoparticles including ferrites are very potential candidates for its versatile application in the fields of engineering, bio medicine and electronics. Here we report the enhancement of magnetic properties of Mn-Ni co-doped cobalt ferrite nanoparticles which have been synthesized using coprecipitation technique. TEM study depicts the single phase nanocrystalline ferrite formation. Cation distribution between the tetrahedral and octahedral sites changes due to doping which is responsible for enhancement of magnetic properties. An exhaustive Rietveld analysis confirmed the rearrangement of the cations between the tetrahedral and octahedral sites. Also the results suggests strengthening of A-B and A-A interactions while weakening of B-B interaction for doped sample. ``Law of Approach'' technique is found to be useful and utilized to extract the detail of magnetic parameters like anisotropy constant, anisotropy field, coercivity.
