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.
