The set of slides begins by discussing the topic NMR of heavy fermion superconductors under the topics heavy fermion materials, superconductivity, and nuclear magnetic resonance. The history of these phenomena is sketched, with particular mention made of CeCu₂Si₂, UPt₃, and UBe₁₃. Unconventional superconductivity, which is non-phonon mediated superconductivity, presents a high T_c (up to ~150 K), and involves a more complicated spin/orbital wave function. The presentation then goes on to give experimental NMR results for U₂PtC₂ and Pu-115’s.
