Recently a phenomenological Ginzburg-Landau (GL) theory has been proposed to describe the occurrence of a locally time-reversal symmetry (T) breaking state near a Josephson junction between unconventional superconductors. In this paper we derive this type of GL free energy microscopically from the t-J model within a slave-boson mean-field approximation. The resulting GL free energy is shown to satisfy the conditions to have a T-violating surface state. The existence of this junction state may explain some of the recent experiments on High-Tc superconductors.
