Description

Nanoparticles of NiMn2O4 were successfully obtained by mixing gelatin and inorganic salts NiCl2.6H2O and MnCl2.4H2O in aqueous solution. The mixture has been synthesized at different temperatures and resulted in NiMn2O4 nanoparticles with crystallites size in the range of 14-44 nm, as inferred from X-ray powder diffraction (XRPD) data. We have also observed that both the average crystallite size and the unit cell parameters increase with increasing synthesis temperature. Magnetic measurements confirmed the presence of a magnetic transition near 110 K
