摘要

Linear response of vortex lines to an AC magnetic field is investigated on the basis of an equation of vortex motion in which both linear pinning force and the Hall force are taken into account. The Hall force (i.e., a transverse force which is perpendicular to the vortex velocity) is much larger than the viscous drag force. An apparent inertial force acts on vortices at a frequency below the pinning frequency and a vortex has an effective mass. Near the resonance frequency, various striking features are predicted to occur: elliptic vortex motion, standing wave excitation and resonance, and anomaly in the AC penetration depth.
