Abstract
We present isothermal magnetization measurements (M,T) for YBa2Cu3O7-d elta single crystals with parallel and perpendicular to the ab planes. The (M,T) curves show temperatures T = T- at which the magnetization M(T-) is independent of the applied field. The results are interpret ed as due to vortex fluctuations of an anisotropic 3-D superconductor.
