To elucidate the nature of the heavy-fermion superconductor U1- xThxBe13, measurements are made of the superconducting and magnetic phase boundaries, and of the dc magnetization as a function of magnetic field and temperature. Heavy-fermion systems are of particular interest as they differ from normal metals in having relatively enormous values of low-temperature specific heat and magnetic susceptibility. The appearance of superconductivity in such media is further surprising and intriguing.

为了阐明重屈服超导体U1-XTHXBE13的性质，测量是对超导和磁相边界的测量，以及DC磁化是磁场和温度的函数。 重点系统特别令人感兴趣，因为它们与正常金属有所不同，在具有相对巨大的低温特异性热和磁敏感性的情况下。 这种媒体中超导性的出现更令人惊讶和有趣。
