- Vortex states in a chiral helimagnet/superconductor bilayer system was investigate, using the Ginzburg-Landau equations.
- When an external magnetic field was large, vortices formed a periodically modulated triangular lattice.
- It was expected an enhancement of a critical current because of a vortex configuration in the chiral helimagnet/superconductor bilayer system.
We study effects of a chiral helimagnet (CHM) on vortex states in a superconductor, solving the Ginzburg-Landau equations in a chiral helimagnet/superconductor bilayer system. We found that vortices form a periodically modulated triangular lattice, because the magnetic field from the chiral helimagnet HCHM oscillates spatially. An increase of a critical current is expected, because vortices are pinned by the HCHM.
