Abstract

Heat capacity measurements were performed on Tl0.8Co4Sb11Sn. An Einstein vibrating behavior for the thallium atoms was found. The inelastic neutron scattering measurements on T0.8Co4Sb11Sn, Tl0.5Co3.5Fe0.5Sb12, and Tl0.8Co3FeSb12 showed a localized vibrational mode, which confirmed this Einstein vibrational behavior. Furthermore, the 56±2 K temperature of the Einstein vibrational mode obtained from the heat capacity measurements showed excellent agreement with the 5 meV energy or 57±2 K values obtained from the neutron scattering measurements.
