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.

为了阐明重费米子超导体U1的性质， xThxBe 13，测量了超导和磁 相边界，以及直流磁化强度作为 磁场和温度。 重费米子系统特别令人感兴趣，因为它们 与普通金属不同的是， 低温比热和磁化率。 的 在这样的介质中出现超导性是更令人惊讶的 也很有趣
