Query: Superconductivity in the Heusler Family of Intermetallics   Several physical properties of the superconducting Heusler compounds,
focusing on two systems (Y, Lu, Sc)Pd2Sn and APd2M, where A=Hf, Zr and M=Al,
In, are summarized and compared. The analysis of the data shows the importance
of the electron-phonon coupling for superconductivity in this family. We report
the superconducting parameters of YPd2Sn, which has the highest Tc among all
known Heusler superconductors.
