Abstract

Effects of filler atoms with different ionic radii Ba, Ce, Y on the lattice thermal conductivity of filled RyFexCo4-xSb12 are systematically investigated. The results show that the lattice thermal conductivity decreases significantly by filling Ba, Ce, Y atoms in Sb-icosahedral voids, and the reducing range of the lattice thermal conductivity increases in order of ionic radii decreasing from Ba2+, Ce3+ to Y3+. The lowest lattice thermal conductivity and strongest rattling actions of filler atoms with respect to scattering of phonons are gained when the Sb-icosahedral voids are partly filled.
