The results indicate that Ga occupies 8j and 8f sites, and substitution of Ga for Fe in SmFe10.7Mo1.3 leads to the expansion of the lattice constants a, c and unit cell volume V, the monotonical decrease of the Curie temperature TC, and the decrease of saturation magnetization and the Fe moments. The magnetocrystalline anisotropy changes from uniaxial to conical plane.
