Dipole-Induced Vortex Ratchets in Superconducting Films with Arrays of Micromagnets
Dipole-Induced Vortex Ratchets in Superconducting Films with Arrays of Micromagnets
We investigate the transport properties of superconducting films with periodic arrays of in-plane magnetized micromagnets. Two different magnetic textures are studied: a square array of magnetic bars and a close-packed array of triangular microrings. As confirmed by magnetic force microscopy imaging, the magnetic state of both systems can be adjusted …
