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 Hc2 (48 K) = 13 T and Hc2(0) can exceed 80–230 T in a high-pressure-fabricated NdO0.82F0.18FeAs bulk sample with Tc of 51 K. We also demonstrate the superior performance of supercurrent density in fields for this new superconductor.
