摘　　要：采用高温高压手段,在压力3.5 GPa、温度900 K的条件下。La-filled skutterudite compounds LaxCo4Sb12(0<x≤1.0)were successfully synthesized at 3.5 GPa and 900 K.The X-ray diffraction results indicate that all synthesized samples exist as a single phase with a crystal structure of CoSb3.The composition-dependent electric transport properties of La-filled CoSb3 have been studied at room temperature.The lattice parameters of the samples increase gradually with the increasing of La content.No La phase is found in the range of x from 0.1 to 1.0.The La-filled skutter...
