This book consists of two parts. In the first part, we investigate the superconducting proximity effect in a clean magnetic structure consisting of two ferromagnetic layered domains with antiparallel magnetizations in contact with a superconductor. Within the quasiclassical Green''s function approach we find that the penetration of the superconducting correlations into the magnetic domains can be enhanced as compared to the corresponding single domain structure. This enhancement depends on an effective exchange field which is determined by the thicknesses and exchange fields of the two domains. In the second part, we study the superconducting proximity effect in a clean nonmagnetic metal in contact with a ferromagnetic superconductor which has a nonunitary f-wave triplet order parameter. Using the quasiclassical Green''s function approach, we solve the Eilenberger equation analytically in a non-self-consistent form. The density of states is obtained in the bulk of...
