Abstract

Filled skutterudite compounds, BayFexCo4-xSb12 (x = 0-3.0, y = 0-0.7), were synthesized by a two step solid state reaction method. Electrical transport properties of BayFexCo4-xSb12 were investigated. The lattice constants of BayFexCo4-xSb12 increased with increasing Ba filling fraction and Fe content. The maximum filling fraction of Ba (ymax) in BayFexCo4-xSb12 increased with increasing Fe content, and was found to be rather greater than that of CeyFexCo4-xSb12. The ymax varied from 0.35 to near 1.0 when Fe content (x) changed from 0 to 4.0. Carrier concentration and electrical conductivity increased with increasing Fe content, and decreased with increasing Ba filling fraction for BayFexCo4-xSb12. At the same x and y, carrier concentration and electrical conductivity of BayFexCo4-xSb12 were larger than that of CeyFexCo4-xSb12.
