摘要：

A possible coexistence of different symmetry order parameters is studied near a surface of d-wave supercoductors. The appearance of a different symmetry order parameter depends sensitively on the surface direction relative to the d-wave order parameter. In the case of d(x)2(-y)2-wave, the (1, 1, 0) surface is the most favorable for coexistence. The coexisting order parameters having +/-pi/2 as their relative phase break locally the time-reversal symmetry near the surface.
