RUI: Magnetic Properties of the Heavy-Fermion Superconductor Uranium (thorium) Beryllide

为了阐明重费米子超导体U1-xThxBe13的性质，测量了超导相界和磁相界，以及直流磁化强度随磁场和温度的变化。重费米子系统特别令人感兴趣，因为它们与普通金属不同，它们具有相对较大的低温比热和磁化率。超导电性在这样的介质中的出现进一步令人惊讶和耐人寻味。

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.
