Abstract

We have carried out de Haas-van Alphen (dHvA) experiments on a ferromagnet CeRh₃B₂ with an extremely high Curie temperature T_C ≃ 120 K and a non-4f reference compound LaRh₃B₂. The dHvA data of LaRh₃B₂ are well explained by the results of energy band calculations. The topology of the Fermi surfaces in CeRh₃B₂ is found to be very similar to that of LaRh₃B₂, possessing wavy but flat Fermi surfaces in the basal plane. Observation of a quasi-one-dimensional electronic state is the first such case in a rare earth compound.
