Abstract
We study the influence of the crystalline electric field (CEF) on the temperature dependence of the resistivity of Ce-based heavy fermions. We investigate the infinite- U degenerate Anderson lattice model including the CEF effect by using 1 / N -expansion method a la Nagoya. As a result, we reproduced the T-dependence of the resistivity exhibiting two peaks and its pressure effect, which works to merge the two peaks, as observed in many heavy fermions.
