Abstract

The structural transition in the La2-xNdxCuO4system is studied through thex=0.45, 0.5 compositions, using neutron powder diffraction. Both compositions could be refined as biphasic systems represented by theI4/mmmand theAbmaspace groups. The presence of T and T' phases could be observed in both compositions. The apical oxygen atom in the copper coordination octahedron can be regarded as the key for structural distortion causing the transition from T to T' structures.
