Abstract
Abstract BaLa x Fe 12− x O 19 (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 La 3+ 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 La 3+ substitution. In addition, for the first time we have reported the Mosssbauer study of BaLa x F 12− x O 19 nanohexaferrites in the present paper.
