The high field phase diagram of cuprates derived from the Nernst effect was presented. The measurements of the Nernst signal in the vortex-liquid state of the cuprates to high fields revealed that vorticity extended to very high fields. It was shown that the upper critical field Hc2(T) curve does not end at Tc0. The line entropy rose steeply to a sharp maximum before decreasing monotonically.
