Universidad de Zaragoza Josephson critical currents in annular superconductors with Pearl vortices 2018 Access copy available to the general public Unrestricted We investigate the influence of Pearl vortices in the vicinity of an edge-type Josephson junction for a superconducting thin-film loop in the form of an annulus, under uniform magnetic field. Specifically, we obtain the exact analytic formulation that allows one to describe the circulating current density and the gauge invariant phase increment ¿f across the junction. The main properties of ¿f and their influence on the critical current pattern Ic(B) are described quantitatively in terms of the loop''s width-to-radius ratio W/R and of the vortex position within the loop rv. It is shown that narrow loops (W/R<0.3) may be well described by the straight geometry limit. However, such approximation fails to predict a number of distinctive features captured by our formulation, such as the node lifting effect of the Ic(B) pattern in wide loops or the actual influence of a vortex pinned at different positions. info:eu-repo/grantAgreement/ES/MINECO/ENE2014-52105-R info:eu-repo/grantAgreement/ES/MINECO/ENE2017-83669-C4-1-R info:eu-repo/semantics/openAccess by-nc http://creativecommons.org/licenses/by-nc/3.0/es/ 1.502 2018 Electronic, Optical and Magnetic Materials 2018 Q1 Condensed Matter Physics 2018 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion 2003 395 Universidad de Zaragoza Dpto.
