Abstract

We investigated the vortex lattice ordering induced by an applied current in thick (700–900 nm) Mo-Re films with strong pinning. Measurements of I-V characteristics as a function of field and at different temperatures were carried out. We found that, as in the case of weakly pinning amorphous samples, dynamic ordering can occur only if the size of the vortex correlated region is at least two times the intervortex distance.
