• 論文の詳細を見る

• We have analyzed the reciprocating motion of a magnet levitated above a YBa_2Cu_3O_x superconductor using a nonlinear mechanical model with a mass, a spring, and a dashpot. We introduced velocity dependence of the pinning effect and the distribution of the pinned flux lines against the strength of the pins into the mechanical model. Improved agreement between experimental reciprocation waveforms and simulated ones was achieved. Nonlinear characteristics of reciprocating motion of the magnet above a superconductor were successfully explained with the improved dragged spring model.
