BaLaxFe12-xO19 (0.05 <= x <= 0.25) nanohexaferrites were synthesized by sol gel auto combustion method. X-ray diffraction study revealed the hexagonal structure of the synthesized nanoferrites without any secondary phase and Rietveld analysis confirmed the P63/mmc space group. The crystallite size was observed to increase (49-63 nm) with the increasing substitution of La3+ ions. The particle size was observed to be in the range 49-63 nm. The remarkable increase in saturation magnetization upto 78.5 emu/g and an increase in magneto-crystalline anisotropic was observed with the increase in La3+ substitution. In addition, for the first time we have reported the Mosssbauer study of BaLaxFe12-xO19 nanohexaferrites in the present paper.
