Abstract

Detailed features of the structural disorder in Nd-Ce-Sr-Cu-O with the T*-structure have been investigated by diffuse scattering in electron diffraction. There exist three types of characteristic diffuse scatterings: a cylindrical-shape, a spike-shape, and spots in addition to the fundamental spots due to the T*-structure. The cylindrical-shape and spike-shape scatterings can be concluded to result from both atomic displacements of 0(2) atoms along the <110> directions, on planes through the apical positions of the CuO5 pyramids, and the ordering of Nd and Sr atoms. On the other hand, the extra spots are understood to be related to displacements of O(1) or O(3) atoms along the c axis.
