Single Crystal Growth, Superconductivity and Fermi Surface Study of Plutonium Compounds

Abstract

Single crystals of plutonium compounds PuRhGa 5 and PuIn 3 are successfully grown. For PuRhGa 5 , anisotropy of the superconducting upper critical field was found and analyzed by the anisotropic mass model, consistent with quasi-two-dimensional electronic states predicted by band calculations. On the other hand, the de Haas–van Alphen oscillation was observed in PuIn 3 . By comparing with the band calculations, it is concluded that 5 f electrons are itinerant in PuIn 3 .
