Description
The structural transition in the La2-xNdxCuO4 system is studied through the x = 0.45, 0.5 compositions, using neutron powder diffraction. Both compositions could be refined as biphasic systems represented by the I4/mmm and the Abma space 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
