چکیده انگلیسی
Polycrystalline samples of (Re1âxFex)6Hf were synthesized by arc-melting method and the phase purity of the samples was confirmed by powder X-ray diffraction method. In this paper, we report the Fe substitution and pressure effect on non-centrosymmetric superconductor Re6Hf. The superconducting transition temperature, TC, is confirmed by the measurements of magnetic susceptibility, electrical resistivity for xâ¤0.22 samples with the temperature down to 2â¯K. We find that the TC is suppressed with the increase of Fe content. The upper critical field Hc2 is larger than the value predicted by the WHH theory and shows a linear temperature dependence down to 2â¯K. When upon the application of external pressure up to 2.5â¯GPa, the TC decreases monotonically at a rate dlnTC/dP of 0.01 GPaâ1.
