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.engjournal articlehttp://dx.doi.org/10.1007/BF02704957https://link.springer.comopen access538.9VorticesAsymmetric pinningRectifierAdiabatic ratchet.Física de materialesFísica del estado sólido2211 Física del Estado Sólido
