| Abstract: | The ultrasonic attenuation in two-band superconductors with non-magnetic and paramagnetic impurities in the presence of persistent currents is studied. The case of high impurity concentrations is considered. Assuming space-independent sound waves, the absorption energy in the case of relatively low frequencies at low and zero temperatures is calculated. |
