Anomalous Hall Coefficient in the<i>f</i>Electron system– Ce Compounds

Abstract

We report the temperature dependence of Hall coefficient of RCu 6 (R: La, Ce, Pr, Nd and Sm), Ce x La 1- x Cu 6 and typical Ce compounds (CeRu 2 , CeSn 3 , CePd 3 , CeCu 2 Si 2 , CeAl 3 , CeInCu 2 , CeAl 2 , CeIn 3 and CeB 6 ) in the temperature range of 0.7 K to room temperature. The f electrons of these substances show a wide variety of behavior including Pauli itinerance, mixed valence, heavy fermion and localized moment system. These characteristics are well reflected in the Hall coefficient. The Hall coefficient of Ce x La 1- x Cu 6 at higher temperatures than 30 K is well fitted by the recent skew scattering Hall effect theory.
