G. Blatter et al., LOW-FIELD PHASE-DIAGRAM OF LAYERED SUPERCONDUCTORS - THE ROLE OF ELECTROMAGNETIC COUPLING, Physical review. B, Condensed matter, 54(1), 1996, pp. 72-75
We determine the position and shape of the melting line in a layered s
uperconductor, emphasizing the importance of electromagnetic interacti
ons in the vortex system. In the limit of vanishing Josephson coupling
we obtain a generic reentrant low-field melting line. Finite Josephso
n coupling pushes the melting line to higher temperatures and fields a
nd a line shape B-m proportional to (1 - T/T-c)(3/2) is found. We cons
truct the low-field phase diagram including melting and decoupling lin
es and discuss various experiments in the light of our results.
