Description

We present the results of low-temperature (1.5-10 K) specific heat measurements of superconducting Heusler compounds Ni2(Nb1-xTx)Sn, (T=Ti, Ta, and x=0, 0.05, 0.10 and 0.20). All the compounds exhibit lattice anomalies, reflected in the specific heat by the relevance of an Einstein term. The decrease in the superconducting transition temperature with increasing concentration is correlated with changes in the electron-phonon interaction. (orig.)
