Observation of dynamic Josephson vortex signatures by MFM. (a) Topographic image of a planar Nb/Cu/Nb junction. (b)– (d) MFM phase maps at different applied out-of-plane magnetic fields. The scan area is 4.3×4.3 μm2. Specific MFM responses associated with Josephson vortices appear as arcs and rings in the phase maps.
WebSuperconducting correlations may propagate between two superconductors separated by a tiny insulating or metallic barrier, allowing a dissipationless electric current to flow(1,2). In the presence of a magnetic field, the maximum supercurrent oscillates(3) and each oscillation corresponding to the entry of one Josephson vortex into the barrier(4). Josephson … WebThe authors use magnetic force microscopy to study the formation of chains of small rings in Josephson junctions, and show the number of rings is equal to the number of flux quanta in the junction. Therefore each ring represents an individual vortex in a one-dimensional vortex chain within the junction.
