Magnetic circuit for Abrikosov vortices: Vortex motion in a periodic labyrinth of magnetic T and I-shaped elements under a superconducting film

•We directly imaged Abrikosov vortex motion in a hybrid structure of soft magnetic T- and I-shaped patterns, similar to those used in bubble domain memories, placed under a superconducting layer. The labyrinth-like trajectories of vortices induced by the TI elements can be easily tuned by moderate in-plane magnetic fields, which can be used for manipulation with vortices in fluxonic devices.
