Abstract

We have succeeded in observing the de Haas-van Alphen effect in PrOs ₄P₁₂ which shows no anomaly down to 50 mK in contrast to PrFe₄P₁₂ and PrRu4P12. The Fermi surface (FS) topology is reasonably explained by the energy band structure calculation based on a full potential linearized augmented-plane-wave method within the local-density- approximation. Whereas the localized nature of 4f-electrons, we have confirmed a highly enhanced cyclotron effective mass up to 18m₀ in PrOs ₄P₁₂, which is enhanced 3.8 times compared to that of LaOs₄P₁₂. No nesting property with q = (1, 0, 0) in the FS of PrOs₄P₁₂ has been confirmed, which suggests both the 4f-electron's contribution and the FS nesting property play the role for the phase transitions in PrFe₄P₁₂ and PrRu₄P ₁₂.
