Y-, Dy-, and Gd-doped neodymium (Nd) superconductors (RE0.1Nd0.9Ba2-Cu3Oy) exhibited sharp resistivity transitions at 92 K. DC susceptibility measurements gave a common curve with diamagnetic onsets at 93 K and transitions complete at ≈50 K. Lattice constants for an assumed orthorhombic structure were calculated from X-ray diffraction measurements. These values were used to create a simulated diffraction pattern with 2 θ values and relative intensities that agreed well with observed values. Oxygen contents determined by instrumental neutron activation analysis, ranged from 14.7 to 15.1±0.1 wt%(6.59≤y in Oy≤6.73). This range of oxygen content for YBa2Cu3Oy gives ≈50-60 K transitions in marked contrast to the 92 K (midpoint) values for the materials of this study.
