摘要:

We report the effect of fluorine doping on the fabrication and superconductivity of the iron-based arsenic oxide SmO1-xF delta FeAs (delta >= x) compound. The fluorine over-doping can greatly reduce the heat treatment temperature and the heat treatment time, meanwhile the superconductivity of the SmO1-xF delta FeAs samples does not reduce. The critical transition temperature (T-c) is as high as 56.5 K for the SmO0.7F0.3FeAs sample prepared by the two-step solid state reaction method at 1120 degrees C for 40 h, the J(c) of the sample is 2.4x10(5) A/cm(2) (10 K, 0 T). T-c of the fluorine over-doped SmO0.7F0.35FeAs and SmO0.7F0.4FeAs samples prepared by the two-step solid state reaction method at 1100 degrees C for 20 h are 56 and 55 K, respectively J(c) of the both samples are 1.9x10(5) and 1.7x10(5) A/cm(2) (10 K, 0 T), respectively.
