Sound attenuation in the superconducting amorphous alloy ZrTiCuNiBe
arXiv:cond-mat/9911038 · doi:10.1063/1.593855
Abstract
The superconducting energy gap and the parameter of the intensity of electron scattering at two-level systems in amorphous ZrTiCuNiBe are determined from the results of measurements of sound attenuation. The mechanism of adiabatic renormalization of the amplitude of coherent tunneling is used for a quantitative description of the peculiarities of sound absorption in the vicinity of critical temperature.
