摘要：

A review is presented of the results of the de Haas-van Alphen measurements in the cerium based intermetallic compounds CeSb and CeB6. A comparison with similar experiments in the isostructural lanthanum analogues and with band structure calculations indicates, that in both compounds the 4f states are localized. CeSb is an example of a semi-metal which exhibits a delicate balance between positive and negative exchange interactions between Ce ions. CeB6 is a typical dense Kondo lattice with strongly enhanced quasiparticle masses. The heavy-fermion mass is found to be strongly magnetic field dependent. The field dependence of the cyclotron mass is consistent with specific heat results. © 1990.
