摘要：

We have studied the double superconducting transition of polycrystalline UPt3+x prepared from a non-stoichiometric melt (-0.06 < x < 0.06). Samples prepared with a Pt deficit show the sharpest double transition, suggesting the binding of oxygen by excess uranium. However, microprobe investigations reveal that impurity phases (UPt2 and UPt5) are formed and that the actual deviation from stoichiometry (-0.01 < x < 0.01) is much smaller than the nominal value.
