Processing, microstructure and property relationships in neodymium oxide doped high temperature superconducting YBa 2 Cu 3 O 7 (Y123) were investigated. It has been observed that a small amount ( 0.25-1 mol%) of Nd 2 O 3 results in the formation of nanosized secondary phases which may have a significant effect on the superconducting properties of melt textured Y123 single crystals. It was further observed that addition of Nd 2 O 3 greater than 1 mol% leads to multiple nucleation during

Melt textured single crystals of Y123 with 1 mol% were successfully grown and characterized with respect to microstructural development and superconducting properties.
