Resumen:
The anomalous Nernst effect in hole-doped cuprates has been interpreted in terms of the existence of a superconducting order parameter well above the transition temperature, Tc(H). In order to improve the understanding of this problem, we have measured the angular field dependence of the Nernst signal in Bi2Sr2CaCu2O8+d single crystals. The experiment was done tilting the magnetic field with respect to the direction of the temperature gradient, above and below Tc(H), with applied .elds up to 16 T. We have found that all the curves are scaled on one curve against the reduced field Hcos(eta) at a fixed temperature.
