Zusammenfassung:	Recent advances on ferromagnetic superconductors, UGe 2 , URhGe and UCoGe are presented. The superconductivity (SC) peacefully coexists with the ferromagnetism (FM), forming the spin-triplet state of Cooper pairs. The striking new phenomena, such as SC reinforced by the magnetic field, are associated with Ising-type ferromagnetic fluctuations. A variety of ferromagnetic ordered moments between UGe 2 , URhGe and UCoGe affords to understand the relation between FM, tricriticality and SC.
