N2 - The anisotropy of high Tc superconductors arises both from the coupling constant and the Fermi surface in the Ginzburg-Landau framework. The anisotropy of the former is expressed by dx2-y2 symmetry. The shapes of the Fermi surface of high Tc superconductors are various and depend on materials and doping ratio. In this paper, we study the anisotropy of the upper critical field Hc2 in the ab plane with dx2-y2 symmetry and with typical shapes of the Fermi surface.
