<br/><br/> The speed of sound in metallic glasses and the permittivity of dielectric alumina layers show the typical low-temperature behavior of amorphous solids. Acoustic measurements from a few kHz to GHz show the influence of the conduction electrons in a massive bulk metallic glass. Measurements of the permittivity at a few kHz surprisingly show an influence of the electrons on the properties of an insulating layer.
