Current-driven transformations of the intermediate-state patterns in type-I superconductors
Current-driven transformations of the intermediate-state patterns in type-I superconductors
Dynamic structure of the intermediate state was studied in pinning-free thick Pb strips using real-time magneto-optical visualization. It is found that topological hysteresis can be lifted by applying sufficiently large transport current. Namely, laminar structure that appears in a static case when magnetic flux exits the sample is turned into …
