Abstract

We review results obtained from vortex-Nernst experiments in cuprates. Evidence for a loss of phase coherence at the Meissner transition Tc0 is derived from vortex-like excitations that persist to high temperature T. Below Tc0, the Nersnt signal provides a determination of the upper critical field Hc2 vs. doping x. Implications for the cuprate phase diagram are discussed.
