摘要：

Measurement has been made of the resonance frequency and amplitude of a superconducting reed performing flexural vibrations as a functions of a longitudinal magnetic field B//a and temperature T. Drastic increases in the resonance frequency and damping are found for B//a less than critical field B//c//2(T). The measured increase of the resonance frequency is in agreement with the theoretical results obtained previously for the diamagnetic behavior produced by rigidly pinned flux lines. The measured small deviations of the resonance frequency from the rigid-pinning field-dependence make it possible to obtain the elastic pinning force (Labusch's parameter alpha ).
