Abstract
The temperature dependence of the electrical resistivity of amorphous metals is calculated using two complementary models of the lattice vibrations. The model which describes uncorrelated Einstein oscillators leads to a very satisfactory fit of the experimental data for CuSn alloys at T>or approximately=10K. The negative temperature coefficients are explained by the temperature dependence of the elastic scattering. The results are interpreted as an indication of strong vibrational disorder. For very low temperatures (T2 is predicted as a result of coherent long-wavelength phonons.Keywords
