Abstract

The phase diagram of (Nd1−xTbx)1.85Ce0.15CuO4 has been studied by resistivity, magnetic susceptibility, x-ray, electron-, and neutron-diffraction experiments. For low-Tb concentrations the samples are superconducting; however, Tc diminishes rapidly with increasing x. For higher Tb concentrations all diffraction studies indicate the long-range lattice deformation characterized by the rotation of the CuO4 squares around the c axis (i.e., the orthorhombic phase recently observed in Gd2CuO4); the structural consequences of the distortion are discussed.
