Vortex Chains and Vortex Jets in MoSi Microbridges

Superconducting bridges exhibit many properties of a Josephson junction, such as the electromagnetic radiation at overcritical currents I > c and steps in microwave-irradiated current–voltage (I–V) curves. These effects stem from periodic motion magnetic flux quanta (vortices) narrowest region bridge. According to Aslamazov Larkin (AL) theory, I–V curve constriction should voltage kinks each time number vortices 1D vortex chain is increased by one. However, presence defects fluctuations, intervortex repulsion stipulates formation 2D jet, which goes beyond AL model. Here, milling one or two slits across MoSi thin strip, we make move vortex–jet vortex–chain fashion, respectively. Unexpectedly, for strip with observe equidistant transport ≃ 2 are rather far assumption ≈ At moment, have no explanation this observation, tending attribute it fast relaxation processes looking forward comparison other superconducting materials.
