Crystallographic and magnetic properties of LaFe_1-xGa_xO₃ (x = 0, 0.1, 0.3, 0.5, and 0.7) were studied using XRD and Mössbauer spectroscopy. The crystal structures were found to be orthorhombic and the lattice parameters a, b, and c were found to decrease with increasing Ga substitution. Mössbauer spectra were obtained at various absorber temperatures ranging from 20 K to 750 K. The Mössbauer spectra were all sextets below T_N and were all singlets above T_N. Asymmetric broadening of the Mssbauer spectral lines at 20 K was explained by the multitude of possible environments for an iron nucleus. As the temperature increases to T_N, a systematic line broadening in Mssbauer spectra was observed and interpreted to originate from different temperature dependencies of the magnetic hyperfine fields at various iron sites.
