Research Abstract

We have investigated the relationship between the filling effect of the rare earth and the microscopic electronic states in caged structure compounds, and obtained the results that the system approaches to the ferromagnetic instability in LaFe_4Sb_<12>, and that the hybridization between 4f and conduction electrons is enhanced in CeFe_4Sb_<12> with increasing the filling fraction by the synthesis under high pressure.
