N2 - Superconductivity and ferromagnetism are competing ordered states of matter. It is shown that in superconductor/ferromagnet/superconductor junctions, the coupled dynamics brings about the novel phenomena: The ferromagnetic resonance induces the DC component of the Josephson current in the junctions. In a superconductor/half-metallic-ferromagnet/superconductor junction, the singlet pairs are converted to the triplet ones and the Josephson coupling occurs accompanied by the back flow of spin current. The recent experiment is discussed in the light of the theory.
