| Abstract: | Measurements of the thermal conductivity of a superconducting metallic glass Zr70Cu30 in zero field and in a magnetic field exceeding the upper critical field allow a quantitative determination of the strength of the phonon-electron scattering for the first time in amorphous metals. The temperature dependence of the residual phonon scattering by localized low energy excitations is similar to that found in insulating glasses. |
