Abstract

We have performed the dHvA measurements on Ce_x La_{1 - x} B₆ and Pr_x La_{1 - x} B₆ compounds to study spin splitting of the Fermi surfaces. In PrB ₆ we have found new frequency branches to confirm that the Fermi surface splits into up and down spin Fermi surfaces, whereas no spin splitting has been found for x = 0.25, 0.5, 0.75. We have also found several new frequency branches in CeB₆. The new frequency branches imply that the Fermi surfaces of up and down spin conduction electrons are significantly different in CeB₆ as well as in PrB₆.
