Abstract
Some samples of La2/3(Ca(1-x)Znx)1/3MnO3 （x = 0, 0.2, 0.4, 0.6, 0.8, 1.0） were prepared by solid-state reaction method at 1623K. The crystal structures of the compounds were studied by X-Ray Diffraction(XRD). All the samples are orthorhombic structure (Pnma), the symmetry has no obvious change with the increase of Zn atom content x. The crystal lattice constants, Mn-O bond length and Mn-O-Mn bond angle varied with the different Zn content, analyzed by the Rietveld method.
