Abstract: The intermediate mixed state under the influence of a transport current was studied using small angle neutron scattering. The internal magnetic domain structure consisting of mixed state domains and flux free Meissner state domains was observed to rearrange at intermediate currents well before the critical depinning current marked by a finite voltage. The local rearrangement can be traced by the changes in the vortex lattice Bragg peak scattering and the current-induced anisotropy of the low-q scattering connected to the internal magnetic domain structure. It is argued, that the local reorganisation prior to the critical depinning current is inherently linked to the interplay of the pinning landscape with the vortex lattice domain structure governed by the physics of the intermediate mixed state.
