Abstract

The anisotropy of high T_c superconductors arises both from the coupling constant and the Fermi surface in the Ginzburg-Landau framework. The anisotropy of the former is expressed by d_x2-y2 symmetry. The shapes of the Fermi surface of high T_c superconductors are various and depend on materials and doping ratio. In this paper, we study the anisotropy of the upper critical field H_c2 in the ab plane with d_x2-y2 symmetry and with typical shapes of the Fermi surface.
