From measurements of I-V characteristics of DyBa2Cu307.5/(¥0.45Pr0.55)Ba2Cu307-5 multilayers, we have experimentally determined the characteristic temperature separating the vortex liquid from the vortex solid. We suggest that the cross-over temperature is determined by the anisotropy given by the a
