We have synthesized new skutterudite compounds, which are typical materials with a cage?like structure, and investigate their crystallographic, transport, thermoelectric properties in order to elucidate the mechanism of thermal conductivity reduction by local anharmonic phonons (rattling effect). We report some experimental evidences about rattling motion in skutterudite compounds and discuss the mechanism., 特集 : 「希土類研究プロジェクトの軌跡」 1. カゴ状希土類化合物における局在非調和フォノンによる熱伝導率低減機構の解明}, pages = {3--7}, title = {カゴ状希土類化合物におけるラットリング効果による熱伝導率低減機構の解明}, volume = {63}, year = {2014}, yomi = {セキネ, チヒロ and カワムラ, ユキヒロ and タケダ, ケイキ and サワグチ, ナオヤ and サカイ, アキラ and ナカネ, ヒデアキ} }
