I will review experimental findings up to now about PuCoGa5 superconductor (TC=18.5k). With theroetical calculations, we can conclude without ambiguity that this is an unconventioanl nodal sc and most probably mediated by AFM spin fluctuations. Given that, Pu sc is a bridging material holding clues to understand the unconventional pairing mechanism from 1K HF SC to 100K cuprate SC.
Then, I will discuss a microscopic theory to explain the unified spin-fermion model.
