Fermi-surface topology and field-dependent effective masses of the filled skutterudite compound PrOs4As12

Abstract:

We report magnetic-field-orientation dependent de Haas-van Alphen (dHvA) experiments on the filled skutterudites PrOs4As12 and LaOs4As12. The Fermi surfaces of the compounds are very similar and in reasonable agreement with bandstructure calculations for LaOs4As12 on a PrOs4As12 lattice. This suggests that the 4f electrons are essentially localized in the paramagnetic phase of PrOs4As12. Whilst the properties of LaOs4As12 suggest a conventional nonmagnetic Fermi liquid, the effects of direct ...
