Abstract
|
|
|
|
| In type-II superconductors, where vortices and antivortices tend to annihilate, only a 'ferromagnetic' vortex lattice, with the same orientation of vortex magnetic moments, is usually formed in a homogeneous external magnetic field. Using the time-dependent GinzburgLandau formalism, we demonstrate that a checkerboard vortexantivortex lattice ('antiferromagnetic vortex lattice'), imprinted onto a superconducting film by a periodic array of underlying clockwise and counterclockwise microcoils generating spatially periodic positive and negative magnetic field pulses and then trapped by an array of artificial pinning centers, remains stable even after the imprinting magnetic field pulse is switched off. |
