摘要：

We discuss the problem of broken time-reversal symmetry near grain boundaries in a d-wave superconductor based on a Ginzburg-Landau theory. It is shown that such a state can lead to fractional Vortices on the grain boundary. Both analytical and numerical results show the structure of this type of state.
