Abstract

Here we report a new quaternary iron-arsenide superconductor Nd[O 1− x F x ]FeAs , with the onset resistivity transition at 51.9 K and Meissner transition at 51 K. This compound has the same crystal structure as LaOFeAs, and becomes the second superconductor after Pr[O 1− x F x ]FeAs that superconducts above 50 K.
