Abstract
Enhancements of the low-temperature thermopower of several La-based and Ca-based glassy alloys are compared with the predictions for the electron-phonon enhancement. The agreement is reasonably good for the La-based alloys, but unexpected structure is observed for the Ca-based alloys. The measurements suggest that the low-frequency alpha 2( omega )F( omega ) is proportional to omega beta with beta >1 for these alloys.Keywords
