U-T (T = Mo, Pd, Pt) alloys were prepared by splat cooling technique and characterized by X-ray diffraction. The resistivity and specific heat measurements were performed down to 0.3 K to study their superconductivity.
The superconducting transition in the alloy with 6 at.% Mo (U-6%Mo) revealed by a smooth decrease below 1.5 K and a sharp drop at 0.6 K in the resistivity, while a single sharp drop was revealed at T-c approximate to 0.8 K for those with 5 at.% Pd and Pt doping (U-5%Pd and U-5%Pt). With applying Magnetic fields, the resistivity drops move to lower temperatures.
The superconductivity transitions were revealed by only one broad peak at T-c in the C(T) curves.
