Abstract
Nd 1+xBa 2−xCu 3O y (NdBCO) bulk materials are known to have superior superconducting properties than YBa 2Cu 3O 7−δ (YBCO). However, several barriers need to be overcome prior to the development of reliable fabrication techniques for these materials. One of these barriers is the required tight control of processing oxygen partial pressure p( O 2), which dictates the degree of Nd 3+ substitution onto Ba 2+-site and consequently affects both T c and J c . In addition, it is difficult to find an appropriate seed with similar lattice structure to and higher melting point than NdBCO, due to its nearly the highest peritectic temperature in the REBCO series. This paper focuses on establishing the growth conditions of Ag-doped, and hence melting point depressed, NdBCO large grains under high p( O 2) of 1–5% using NdBCO seeds introduced either at room temperature or near the peritectic temperature of NdBCOAg. The superconducting properties of the large NdBCOAg grains fabricated following the optimized conditions were also characterized.
