Abstract

We report the first successful observation of the de Haas-van Alphen effect in the filled skutterudite LaRu₄P₁₂. Observed Fermi surfaces (FSs) are close to those expected from the band calculation. The effective mass m_c^* is roughly twice compared to the calculated band mass. Assuming the similarity of FS between LaRu₄P₁₂ and PrRu₄P₁₂, the FS nesting with q = (1, 0, 0) as a possible origin of the M-I transition in PrRu₄P₁₂ is discussed.
