摘要：

Measurements of magnetic susceptibility, specific heat, and electrical resistivity have been performed on the ACoGa(5) (A=U, Np, Pu, Am) series. The electrical resistivity of UCoGa5 and PuCoGa5 can be scaled upon the rho(T) data of the heavy-ferinion superconductor CeColn(5) indicating a single spin fluctuation energy scale dominates the transport properties. The physical properties of the ACoGa(5); materials suggest the PuCoGa5 superconductor resides near an itinerant/localized crossover of the 5f electrons and is remarkably similar to the one that occurs in the light actinide elements.
