Abstract

Low-temperature specific heat and elastic moduli measurements are reported for Ca-based bulk metallic glasses. The deviation from the Debye behaviour observed in the specific heat is modelled with a simple Einstein oscillator with characteristic temperature 80 K. The presence of this local mode can also account for the deviation from normal ‘Varshni behaviour’ observed in the temperature dependence of the elastic moduli.
