Abstract

Vortex structures in the ferromagnet/type-II superconductor bilayer are investigated when the ferromagnet has domain structure and perpendicular magnetic anisotropy. It is found that two equilibrium vortex structures can be realized: straight vortices with alternating directions corresponding to the direction of the magnetization in the ferromagnetic domains and vortex semi-loops connecting the ferromagnetic domains with opposite direction of the magnetization. The values of the critical magnetization for the formation of these vortex structures are determined.
