Abstract
The time-dependent Ginzburg–Landau equations have been solved numerically by a finite element method for a hybrid system consisting of a finite-size superconducting film with a magnetic strip on top. It is demonstrated that the coexistence of vortices and antivortices could occur in the mesoscopic superconducting film due to the important influence of the magnetic strip, which could help us to understand the experimental results.
