Magnetic and transport characteristics in the uranium intermetallic compounds with the HoCoGa-type structure

Haga, Yoshinori   

Physical properties of actinides compounds are mainly dominated by the 5f electrons behavior. Among a series of actinides compounds, so-called 115 compounds crystallizing in the tetragonal HoCoGa-type structure have extensively been studied because of unusual correlated electronic states, including heavy effective mass of conduction electrons, magnetic orderings and heavy fermion superconductivity. We discuss the origin of peculiar behavior arising from uranium 5f electrons.
