Title

Continuation: Self Organisation of the IMS under the Application of a Current

Abstract

The microscopic coexistence of complete flux expulsion (Meissner state) and the penetration of an array of supercurrent vortices (mixed state) in the intermediate mixed state (IMS) is one of the most prominent examples of intertype behavior in superconductors (SC), outside the type I/II dichotomy. More than 50 years after its first observation via Bitter decoration, the IMS is still an ongoing research topic, relevant not only for the understanding of exotic magnetic matter in SC, but more importantly due to its role as a model system for universal domain physics, e.g., shown by the analogy of clusters of magnetic Skyrmions in the cubic helimagnet Cu2 OSeO3. We have established the existance of the IMS in the steady state flux flow and observed an elongation of the IMS spatial domains indicative of a self organisation towards a stripe pattern orthogonal to the applied current in the direction of the flux line movement (5-31-2748 and EASY-568 beamtimes, a paper is in progress). In this continuation proposal we want to (i) study the effect of the mixed state filling factor on the rearrangement process and (ii) investigate the magnetic field dependant spatial current distribution.
