LaGa_1-xCr_xO₃(x=0,0.2,0.4,0.6,0.8,1.0) were synthesized by solid state reaction for the first time. The effects of chromium ion substitution on the structure,IR spectra,electric properties and magnetic properties of LaGa_1-xCr_xO₃ were investigated.Some regularities of changes were obtained.The results show that Cr³⁺ enters into lattice and induces the lattice distortion of compounds.The Ga-O stretching vibrations and O-Ga-O deformation vibrations are shifted to high frequencies after substitution of Cr³⁺ for Ga³⁺.The resistivity decreases and susceptibility increases as the concentration of Cr³⁺ increases.
