摘要
We investigate analytically and numerically the melting of the vortex lattice moving in an inhomogeneous environment under the applied current j. We predict the existence of a dynamic phase transition at some characteristic current j=jt (crystallization current) from the motion of the amorphous vortex configuration at j<jt to the motion of the vortex crystal at j>jt. The crystallization current jt exceeds essentially the critical current jc for strongly disordered systems and diverges as temperature approaches the melting temperature Tm of the undisturbed lattice. © 1994 The American Physical Society.
