- Аннотация: Made of a thin non-superconducting metal (N) sandwiched by two superconductors (S), SNSJosephson junctions enable novel quantum functionalities by mixing up the intrinsic electronicproperties of N with the superconducting correlations induced from S by proximity.Electronic properties of these devices are governed by Andreev quasiparticles which areabsent in conventional SIS junctions whose insulating barrier (I) between the two S electrodesowns no electronic states. Here we focus on the Josephson vortex (JV) motion insideNb-Cu-Nb proximity junctions subject to electric currents and magnetic fields. The resultsof local (magnetic force microscopy) and global (transport) experiments provided simultaneouslyare compared with our numerical model, revealing the existence of several distinctdynamic regimes of the JV motion. One of them, identified as a fast hysteretic entry/escapebelow the critical value of Josephson current, is analyzed and suggested for low-dissipativelogic and memory elements.
