Abstract

Nernst and magnetization experiments reveal the existence of a large region of the cuprate phase diagram above the T_c curve in which vorticity and weak diamagnetism exist without phase coherence. We discuss the implication that the transition at T_c is caused by the loss of long-range phase coherence caused by spontaneous vortex creation. Below T_c, these measurements provide an estimate of the depairing field H_{c 2} which is found to be very large (40 - 100 T depending on doping). We discuss the high-field Nernst and magnetization results, binding energy, and the phase diagram of hole-doped cuprates. Some new magnetization results on the vortex liquid in very underdoped LSCO in the limit T → 0 are reported as well.
