Abstract

The Ginzburg-Landau theory is used to estimate the d-wave correction to the critical field Hc2 and to Hc3, the superconducting critical field in the presence of a surface. The correction to Hc3 is dependent on the angle of orientation of the crystal lattice with respect to the surface of the sample while that due to Hc2 is a constant. This angular-dependent shift in Hc3, if experimentally observable, would be an indication of the pairing state of the superconductor.
