摘要:
In this paper we report the fabrication and superconducting properties of GdO1-xFxFeAs.It was found that when x is equal to 0.17,GdO0.83F0.17FeAs is a su-perconductor with the onset transition temperature Tonc≈36.6 K.Resistivity anomaly near 130 K was observed for all samples up to x = 0.17,and such a phenomenon is similar to that of LaO1-xFxFeAs.Hall coefficient indicates that GdO1-xFxFeAs is conducted by electron-like charge carriers.
