In a superclean limit the Magnus force on Abrikosov vortices is stronger than friction. Due to this, nondissipative force vortex segments rotate around pinning centers. Waves of such rotations under certain conditions are only weakly damped (not overdamped as is usually the case) and lead to resonances in the ac response. (The excitation of such waves by applied ac field near the surface is considered. Surface impedance, ac resistivity, and magnetic permeability are calculated using elasticity theory of the vortex lattice.
