Abstract
We report here the main results of superconductivity measurements on a La-Zn 22 at % alloy, in amorphous and crystalline (hexagonal metastable phase) forms. The experimental details and a complete discussion of these results will be published elsewhere. The superconducting and relevant electronic properties have been extracted from specific heat, upper critical field and electrical resistivity measurements. The difference in the superconducting behaviour between the amorphous and crystalline states is compared to theoretical predictions. In conjunction with other results those presented here throw light on the problem of the electron-phonon coupling strength in amorphous transition metals alloys.
