abstract

  • Enhancements of the low-temperature thermopower of amorphous melt-quenched (Zr0.64Ni0.36)1-xAlx alloys with x=0, 0.05 , 0.10, 0.15, 0.20 and 0.25 are shown to be in good agreement with the predictions for the electron-phonon enhancement. The results imply that the low-frequency part of the Eliashberg function alpha 2( omega ) F( omega ) is proportional to omega n with n>1 for these alloys. These alloys are weak-coupling superconductors, and the addition of Al reduces the electron-phonon coupling constant lambda despite the tendency to strong coupling in simple amorphous metals.
