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 0.3K to study their superconductivity. The superconducting transition in the alloy with 6at.% Mo (U–6%Mo) revealed by a smooth decrease below 1.5K and a sharp drop at 0.6K in the resistivity, while a single sharp drop was revealed at Tc≈0.8K for those with 5at.% 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 Tc in the C(T) curves.
