Abstract

We have prepared polycrystalline samples of the superconducting oxides NdxY1-xBa2Cu3Oy with x=0, 0.1, 0.5, 0.9, and 1.0. A SEM investigation indicates, for neodymium containing samples, 20 micron size particles in the interior and a "basket weave" morphology on the pressed surface. EDX and x-ray diffraction reveal no indication of rare earth segregation in the alloys. The in-plane lattice constants increase by 1% with x, but ther is no variation in the orthorhombic splitting (b/a-1 = 2%). All samples have transition (50% resistance) temperatures between 91 K and 92 K.
