AC current driven dynamic vortex state in YBa2Cu3O7-x
Source abstract
Abstract
Time-resolved magneto-optical imaging measurements show that an ac current enables the vortex matter in YBa2Cu3O7-x thin films to reorganize into two coexisting steady states of driven vortex motion with different characteristics: a quasi-static disordered glassy state in the sample interior and a dynamic state of plastic motion near the edges. Finite-element calculations consistent with the critical state model show good agreement with the measured field profiles in the quasi-static state but predict a larger hysteretic behavior in the dynamic state.
