Abstract

Superconductivity and structural characterization is reported for the Heusler structure compounds ScRh ₂ Sn, LuRh ₂ Sn, and YRh ₂ Sn. The superconducting Tc 's are 2.0 K, 2.9 K, and 4.1 K, respectively. The electronic contributions to the specific heat and the Debye temperatures are reported, and suggest that the observed trend in Tc is governed primarily by an increase in electron-phonon coupling on going from ScRh ₂ Sn to YRh ₂ Sn. The electron-phonon coupling constant λep and the normalized specific-heat jump ΔC/γ Tc suggest that the MRh ₂ Sn system evolves from weak coupling to moderate coupling superconductivity.
