Very High Critical Field and Superior J(c)-Field Performance in NdFeAsO0.82F0.18 with T-c of 51 K
A new family of oxypnictide superconductors, LaFeAsO0.89F0.11, brings new impetus to the field of high-temperature superconductivity. In this work, we show that the upper critical field values H,2 (48 K) = 13 T and H-c2(0) can exceed 80-230 T in a high-pressure-fabricated NdO0.82F0.18FeAs bulk sample with T-c of 51 K. We also demonstrate the superior performance of supercurrent density in fields for this new superconductor.
