Abstract

Features of diffuse scattering in La1.8-xSmxSr0.2CuOz have been investigated by means of electron diffraction. There exist two types of diffuse scatterings in the T- and T*-structures, which are, respectively, observed as a {100}* planar diffuse scattering and a cylindrical-shape one along c axis in reciprocal space. Because the features of the latter scattering is basically identical to those observed in NdCeSrCuO with the T*-structure, it is understood that the characteristic structural disorder due to static displacements of atoms commonly exists in superconducting oxides with the T*-structure.
