Abstract

We have investigated the de Haas-van Alphen effect in the Pr-based heavy fermion superconductor PrOs $_{4}$ Sb $_{12}$ .The topology of Fermi surface is close to the reference compound LaOs $_{4}$ Sb $_{12}$ and well explained by the band structure calculation based on the FLAPW-LDA+U method, where the 4{\it f} electrons are localized. We have confirmed a highly enhanced cyclotron effective mass 2.4 $\sim 7.6 m_{0}$ which is apparently large compared to the usual Pr-based compounds.
