Dynamic reorganization of vortex matter into partially disordered lattices

Abstract

We report structural evidence of dynamic reorganization in vortex matter in clean NbSe${}_2$ by joint small angle neutron scattering and ac-susceptibility measurements. The application of oscillatory forces in a transitional region near the order-disorder transition results in robust bulk vortex lattice configurations with an intermediate degree of disorder. These dynamically-originated configurations correlate with intermediate pinning responses previously observed, resolving a long standing debate regarding the origin of such responses.
