Surface superconductivity is studied within Ginzburg-Landau theory for two classes of models for the order parameter of (Formula presented). The first class assumes two independent one-dimensional order parameters (AB models), while the second assumes a single two-dimensional order parameter (E models). (Formula presented) is calculated for all cases where the surface normal and magnetic field lie along high-symmetry directions. Assuming specular reflection, it is found that except when H∥c^, the ratio (Formula presented)/(Formula presented) is either unity or equals its “s-wave” value 1.695, although the precise (Formula presented) vs T curve predicted by the AB and E models differs for various geometries. The results are compared with recent experiments, and predictions are made for future experiments.
