The present study focuses on the development of a new route for the synthesis of pure nickel borate nanoparticles using reverse micellar route. Nickel borate nanoparticles (25 nm) were synthesized from a precursor (obtained by reverse micellar route) containing both nickel and boron (nickel nitrate and sodium borohydride as starting materials). Decomposition of the precursor at a temperature of similar to 800 degrees C yielded pure nickel borate nanoparticles. This was confirmed by powder X-ray diffraction and transmission electron microscopy. These nanoparticles show an antiferromagnetic ordering with Neel temperature of 47 K.
