Abstract: The Nambu spinor Green’s function approach is applied to studying the proximity effect in ferromagnet/d-wave superconductor (FM/d-wave SC) junctions. It is found that the magnitude of the proximity effect depends to a great extent on the orientation of the SC crystal with respect to the interface normal. On the FM side, near the interface there are two different types of density of states (DOS) with superconducting features. On the SC side, the DOS near the interface is spin dependent, indicating a local coexistence of weak ferromagnetism and d-wave superconductivity. Copyright Springer-Verlag Berlin/Heidelberg 2004
