摘要：

We determine the position and shape of the melting line in a layered superconductor, emphasizing the importance of electromagnetic interactions in the vortex system. In the limit of vanishing Josephson coupling we obtain a generic reentrant low-field melting line. Finite Josephson coupling pushes the melting line to higher temperatures and fields and a line shape B-m proportional to (1 - T/T-c)(3/2) is found. We construct the low-field phase diagram including melting and decoupling lines and discuss various experiments in the light of our results.
