Experimental adiabatic vortex ratchet effect in Nb films with asymmetric pinning trap

  • Published:
Pramana Aims and scope Submit manuscript

Abstract

Nb films grown on top of an array of asymmetric pinning centers show a vortex ratchet effect. A net flow of vortices is induced when the vortex lattice is driven by fluctuating forces on an array of pinning centers without reflection symmetry. This effect occurs in the adiabatic regime and it could be mimiced only by reversible DC driven forces.
