Ultra High Resolution SANS Study of the IMS Domain Morphology with Transport Current
In Niobium we find due to a rare attractive vortex-vortex interaction the intermediate mixed state (IMS) consisting of flux-free Meissner state domains and mixed state domains. Applying a transport current to a superconductor can induce the flux flow state, where vortices of the mixed state are depinned and start moving orthogonal to the applied current. In a recent study (Brems 2022 Supercond. Sci. Technol. 35 035003) we observed the current-induced self-organisation of the IMS to stripes oriented orthogonal to the applied current. Due to Amperes law the current is constrained to areas with non-vanishing curl of B, e.g., to the mixed state domains and its interfaces. Given the stripe superstructure, the question that directly arises is how can the current pass across a Meissner domain separating two mixed state stripes? In this detailed follow-up study we want to answer that question using an ultra high resolution setup: By further extending the low-q limit we will be able to resolve the correlation peak of the IMS domain structure and observe the length scales of the IMS domains in horizontal and vertical direction distinguishing between the bridge and perfect stripe scenario.
