- 論文の詳細を見る
The magnetic, transport and thermal properties of alkaline-earth-filled skutterudites AFe_4Sb_<12> (A=Ca, Sr, Ba) are reported. All three compounds show maximum magnetic susceptibility and thermopower at 50K and a large electronic specific heat coefficient of 100mJ/mol K^2. The electrical resistivity exhibits a shoulder at 70K and follows quadratic temperature dependence below 9K. These properties are the characteristics of a nearly ferromagnetic metal. The suppression of ferromagnetic spin fluctuations of the Fe 3d band by applying magnetic fields was manifested as a negative magnetoresistance between 50 and 80K.
