The investigation of the induced magnetization in the ferromagnetic Josephson junctions is presented. The noncollinear magnetization of the ferromagnetic layers provides the conditions necessary to generate triplet superconducting correlations. It leads to the long-range induced magnetic moment, emerging in the superconducting layers. The induced magnetic moment, provided by the bands electrons, have been calculated in a variety of Josephson junctions with multilayered ferromagnetic weak link. It is shown to be dependent on the Josephson phase that provides a coupling between the Josephson and the magnetic dynamics. By tuning the Josephson current, one may control the long-range induced magnetic moment. Alternatively, applying the voltage we can generate an oscillatory magnetic moment. The detection of such a spin effect may serve as independent evidence of the triplet superconductivity. The proposed mechanism seems to be attractive for superconducting spintronic devices with low dissipation.
