摘要：

We calculate the angular dependence of the upper critical field Hc2, taking account of the effect of the gap anisotropy and nonlocal correction. If the Fermi surface is nearly isotropic in the a-b plane, the results show that the angular dependence of the upper critical field for LaSrCuO4 in the a-b plane is qualitatively explained by an order parameter Δ with the symmetry of the pairing state dx2-y2, consistent with a recent experiment by Raman spectroscopy. © 1995 The American Physical Society.
