%X FeS_2(pyrite) doped by rare earth(Nd) is prepared by annealing at high temperature in a sulfur atmosphere.The structural and photoelectrical properties of samples are studied by X-ray diffraction patterns and optical absorption spectra.The procedure used is the full profile refinement of X-ray diffraction patterns using the Rietveld method.The experimental results show the change of unit cell volume of the sample dopping of rare earth,which leads to the change of properties of the sample.
