Model for current-driven motion of magnetic bubble lattices
Abstract
A model (with no free parameters) for the current-driven motion of magnetic bubble lattices is developed, consisting of massless damped elements (bubbles) connected by linear springs (representing the bubble-bubble interaction). For the specific system considered, the model yields a saturation velocity of about 1 m/sec, in agreement with experiment. The variation of bubble diameter is not explicitly computed; treatment of this additional degree of freedom should produce a still more realistic model.
