Abstract：
Perovskite oxides LaFe _1－xCr _xO ₃were synthesized by solid state reaction method. X-ray powder diffraction was tested to characterize the crystalline structure of the samples. The result indicates that the samples are single orthorhombic phase. The lattice parameter decreases with the Chromium concentration. The extend X-ray absorption fine structures (EXAFS) of the Fe K-edge as a function of doping level x show that the Fe-La bonds distance decreases dramatically. This suggests that Lanthanum is very important for the stability of the whole LaFe _1－xCr _xO ₃structure.
