A possible explanation is given for the anomalous electrical resistivities of Puand Pull. which show maxima at low temperatttres where the susceptibilitiesshow no remarkable temperature dependence. We study a mechanism in whichthe s-wave conduction electrons mixed with the f electrons by the s-f hybridizationare scattered by the spin fluctuations of the f electrons via tlte f-f Coulomb in-teraction. The decrease in the resistivity at higher temperatures is due to thebreakdown of the s-f hybridization (dehybridization) owing to the thermallyenhanced spin fluctuations. The dehybridization effect and the temperaturedependence of the resistivity strongly depend on the width and the structure ofthe f band. For favorable structure of the f band the calculated resistivity showsa maxzmum.
