Abstract :

Ni-Mn ferrite nanoparticles have been synthesized using carboxylate precursor via thermal decomposition route. The prepared precursor Ni0.8Mn0.2Fe2 (PhAc)3 (N2 H4 )5 was characterized by hydrazine, metal analyses, infrared spectral and thermal analyses. Using appropriate annealing conditions, Ni0.8Mn0.2Fe2 O4 nanoparticles of average size 13 nm were synthesized by thermal treatment of the precursor. The nanoparticles were characterized by using X-ray diffraction (XRD), Scanning Electron Microscope (SEM), High Resolution Transmission Electron Microscope (HRTEM) and Selected Area Electron Diffraction (SAED) techniques. The details of synthesis and characterizations of the nanoparticles are reported in this paper.
