Abstract: We review experimental and theoretical studies of two new superconductors, B-doped diamond and PuMGa5 (MZCo, Rh). The pairing mechanism responsible for superconductivity in these materials remains ambiguous. Though electron phonon pairing in B-doped diamond is a viable candidate, the Coulomb interaction in this poor metal must be understood before definitive conclusions can be drawn. The 5f electrons of Pu appear to play a decisive, but uncertain, role in producing superconductivity in PuMGa5. The possibility of magnetically mediated superconductivity in these materials is suggested by analogy to the evolution of superconductivity and magnetism in isostructural Ce- and actinide-based materials.
