摘要：

We present results of magnetisation, resistivity, thermopower and thermal conductivity measurements on the compound Eu0.83Fe4Sb12, which orders magnetically below 84K. An interesting feature of this compound is the large positive magnetoresistance. reaching values of 130% at 2K and 12T, and still 30% at room temperature. Fe/Co substitution causes a drop in the magnetic ordering temperature T-mag and an increase of the thermopower values, which is expected from a decrease of the charge carrier density.
