Superconductivity in U-T alloys (T = Mo, Pt, Pd, Nb, Zr) stabilized in the cubic γ-U structure by splat-cooling technique
چکیده انگلیسی


• Stabilization of cubic gamma-U phase down to room temperature by splat cooling technique.
• Ultra-fast cooling reduces the required doping content and increase the solubility.
• U-T splats become superconducting with Tc in the range of 0.61 K–2.11 K.
• The BCS superconductivity was observed in U-15at.% Mo alloy.

We succeed to retain the high-temperature (cubic) γ-U phase down to low temperatures in U-T alloys with less required T alloying concentration (T = Mo, Pt, Pd, Nb, Zr) by means of splat-cooling technique with a cooling rate better than 106 K/s. All splat-cooled U-T alloys become superconducting with the critical temperature Tc in the range of 0.61 K–2.11 K. U-15 at.% Mo splat consisting of the γ-U phase with an ideal bcc A2 structure is a BCS superconductor having the highest critical temperature (2.11 K).
