Abstract:	We study Josephson effect in d-wave superconductor/diffusive ferromagnet/d-wave superconductor junctions, changing the exchange field and the angles between the normal to the interfaces and the crystal axes of d-wave superconductors. We find a 0–π transition at a certain value of the exchange field. In the presence of midgap Andreev resonant states (MARS), the maximum Josephson current has a double peak structure as a function of temperature due to the exchange field and the competition between the proximity effect and the MARS.
