本文报道了一种新的四元铁砷化物超导体Nd[O（1-x）F（x）]FeAs，其电阻率转变起始温度为51.9K，Meissner转变起始温度为51 K。该化合物具有与LaOFeAs相同的晶体结构，是继Pr[O（1-x）F（x）]FeAs之后第二个在50 K以上超导的超导体。版权所有（c）EPLA，2008年。
Here we report a new quaternary iron-arsenide superconductor Nd[O(1-x)F(x)]FeAs, with the onset resistivity transition at 51.9K 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 50K. Copyright (c) EPLA, 2008.
