Abstract

We propose a possible strategy of calculating physical quantities in normal states of Ce compounds, in the presence of a crystalline electric field (CEF). In particular, we show the specific heat γ and magnetic susceptibility χ cannot be estimated without correctly treating the CEF splitting and renormalization effect due to electron correlation. In the study, we discuss CeCoIn 5 as a typical example, and estimate γ and χ on the basis of the tight binding model which is suitable for CeCoIn 5 . Throughout the paper, we show how to treat electron correlation in order to construct a renormalized electronic structure. Using the renormalized electronic structure, we obtain reasonable values for physical quantities.
