It is shown that superconductivity and ferromagnetism can coexist in systems that are unstable to restructuring of the single-particle electron spectrum with formation of a Bose condensate of triplet electron-hole pairs (spin wave density) and containing localized moments. The ordering of the localized magnetic moments is due to both intraband and interband RKKY interactions. The latter can be treated as exchange of triplet electron-hole pairs. In this system the coexistence is possible even at arbitrarily weak exchange scattering. The Curie temperature in this system is higher than the superconducting-transition temperature.
