摘要：

The de Haas-van Alphen (dHvA) effects have been studied in an antiferromagnetic heavy Fermion compound CeRh2Si2 with fields in the high symmetry planes of (001), (1 (1) over bar 0) and (010). More than twenty separate dHvA branches have been observed ranging from 33 T to 9170 T; most of the branches are observed in limited regions of the field directions: The largest cyclotron mass obtained is 4.4 m(0), which is rather small compared to the estimate from the Sommerfeld coefficient. This implies that heavy Fermi surfaces remain uncovered.
