Direct observation of stress accumulation and relaxation in small bundles of superconducting vortices in tungsten thin films 2011 Access copy available to the general public Unrestricted We study the behavior of bundles of superconducting vortices when increasing the magnetic field using scanning tunneling microscopy and spectroscopy at 100 mK. Pinning centers are given by features on the surface corrugation. We find strong net vortex motion in a bundle towards a well-defined direction. We observe continuous changes of the vortex arrangements, and identify small displacements, which stress and deform the vortex bundle, separated by larger rearrangements or avalanches, which release accumulated stress. info:eu-repo/grantAgreement/ES/MICINN/CSD2007-00010 info:eu-repo/grantAgreement/ES/MICINN/MAT2008-06567-C02 info:eu-repo/grantAgreement/ES/MINECO/FIS2008-00454 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 7.37 2011 PHYSICS, MULTIDISCIPLINARY 5 / 82 = 0.061 2011 Q1 T1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Suderow, H.
