Abstract

Interaction of the magnetic flux flow with the crystal lattice in type-II superconductors is studied. Expression for the elastic stress is derived and previous works on the subject are critically analyzed. The power and spectrum of the acoustic waves generated by the moving flux lattice is computed. Our results, while qualitatively and quantitatively different from the results of Ivlev et al. [Phys. Rev. B 60, 12419 (1999)], confirm their prediction that generation of ultrasound by the moving vortex lattice can be detected in experiment.
