Experimental vortex ratchet effect in nanostructured superconductors Villegas, J. E. González Herrera, Elvira María González, M. P. Nuñez, N. O. Anguita, J. V. Vicent López, José Luis Superconducting Nb thin films were grown on different arrays of triangle-shape metallic islands. The vortex lattice dynamics could be strongly modified by these asymmetric vortex traps. These asymmetric pinning potentials lead to a rectification effect on the vortex motion: Injecting an ac supercurrent on the sample yields a net dc vortex flow. This vortex ratchet ffect is adiabatic and reversible: The effect is frequency independent and the polarity of the dc voltage output could be tuned by the applied magnetic fields and the input ac currents. 2023-06-20T13:44:34Z 2023-06-20T13:44:34Z 2023-06-20T13:44:34Z 2006 book part https://hdl.handle.net/20.500.14352/53561 XXXX-XXXX 10.1063/1.2354978 eng AIP Conference Proceedings MAT2002-04543 NAN2004-09087 MAT2002-12385-E 6R/MAT/0617/2002 open access Amer Inst Physics
