Abstract

Single crystals of plutonium compounds PuRhGa₅ and PuIn₃ are successfully grown. For PuRhGa₅, 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 PuIn₃. By comparing with the band calculations, it is concluded that 5f electrons are itinerant in PuIn₃.
