Abstract
It is shown that a locally time-reversal symmetry breaking state can o ccur at Josephson junctions between unconventional superconductors due to the angular structure of their pair wave function. The origin is t he order parameter induced by the proximity effect at the junction, wh ich can combine with the bulk order parameter with a nontrivial relati ve phase. Experimental consequences of this effect in high-temperature superconductors are examined.
