The induced magnetic moment, provided by the bands electrons, is calculated in a variety of ferromagnetic Josephson junctions (FJJs) with multilayered weak link. The triplet superconducting correlation may lead to the long-range induced magnetic moment, emerging in the superconducting layers and depending on the Josephson phase. This mechanism provides the direct coupling of magnetic dynamics with the Josephson one that may find applications in spintronics. The distribution of the induced magnetization has been measured just recently by neutron scattering and described by the developed model for a strong ferromagnet. The triplet superconducting correlation may cause due to noncollinear magnetization of the magnetic layers or its domain structure. The role of the latter in the formation of the long-range Josephson current is also analyzed. At the end, few words about recent state in the low-temperature nanoelectronics, where described effects could be applied.
