For Gd[sub 2]CuO[sub 4], a new symmetry-forbidden phonon for the tetragonal T[prime] structure is observed. This implies that oxygen in the CuO[sub 2] plane is locally distorted along the CuO[sub 2] plane. Such distortion has never been observed for other T[prime]-type superconductors, which show superconductivity by Ce doping. The disappearance of superconductivity for Gd can be correlated with the appearance of the distortion due to oxygen in the CuO[sub 2] plane. 8 refs., 1 fig.
