Superconductivity in U-T Alloys (T = Mo, Pt, Nb, Zr) Stabilized in the Cubic γ-U Structure

Year: 2016

Type: article

Abstract: Using ultrafast cooling (with the cooling rate up to 10 6 K/s) helps to minimize the T-alloying concentration (T = Mo, Pt, Pd, Nb, Zr) necessary to retain the γ-U phase down to low temperatures.All investigated splat-cooled U-T alloys become superconducting with Tc in the range of 0.61-2.11K.The bulk character of superconductivity can be concluded for some of the splats when comparing the specific-heat anomaly at Tc with the BCS theory prediction.
