Nano size lithium ferrite was prepared through aerosol route and characterized using TEM, XRD, magnetic measurements and Mössbauer spectroscopy. The particle size of as obtained samples were found to be ~10 nm through TEM, that increases upto ~80 nm on annealing at 1200 C. The unit cell parameter ‘a’ calculated using XRD, confirms the formation of α-LiFe5O8. Room temperature Mössbauer spectra o...
