Magnetic field-induced dissipation-free state in superconducting nanostructures 2013 Access copy available to the general public Unrestricted A superconductor in a magnetic field acquires a finite electrical resistance caused by vortex motion. A quest to immobilize vortices and recover zero resistance at high fields made intense studies of vortex pinning one of the mainstreams of superconducting research. Yet, the decades of efforts resulted in a realization that even promising nanostructures, utilizing vortex matching, cannot withstand high vortex density at large magnetic fields. Here, we report a giant reentrance of vortex pinning induced by increasing magnetic field in a W-based nanowire and a TiN-perforated film densely populated with vortices. We find an extended range of zero resistance with vortex motion arrested by self-induced collective traps. The latter emerge due to order parameter suppression by vortices confined in narrow constrictions by surface superconductivity. Our findings show that geometric restrictions can radically change magnetic properties of superconductors and reverse detrimental effects of magnetic field. info:eu-repo/grantAgreement/ES/MICINN/ACI-2009-0905 info:eu-repo/grantAgreement/ES/MICINN/CSD2007-00010 info:eu-repo/grantAgreement/ES/MINECO/FIS2010-2188 info:eu-repo/grantAgreement/ES/MINECO/FIS2011-23488 info:eu-repo/grantAgreement/ES/MINECO/MAT2011-27553-C02 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 10.742 2013 MULTIDISCIPLINARY SCIENCES 3 / 56 = 0.054 2013 Q1 T1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Baturina, T.I.
