中文摘要Using first-principles calculation, we investigate systematically the properties of ZrNi2Ga with fcc L2(1) Heusler structure, including the electronic structure, phonon dispersion, electron-phonon interaction and thermodynamics. The calculated electron-phonon coupling constant lambda and the logarithmically averaged frequency (log) are 0.747 and 68.48 cm(-1), respectively, giving the superconducting transition temperature T-c = 3.15 K according to the Allen-Dynes formula. It is in good agreement with the corresponding experimental T-c and ZrNi2Ga therefore can be explained as a conventional phonon-mediated superconductor.
