The effect of magnetic fluctuations on the critical behaviour of unconventional ferromagnetic superconductors (UGe 2 , URhGe, etc.) and superfluids is investigated by the renormalization group method. For the case of isotropic ferromagnetic order a new unusual critical behaviour is predicted. It is also shown that the uniaxial and bi-axial magnetic symmetries produce fluctuation-driven phase transitions of first order. The results can be used in interpretations of experimental data and for a further development of the theory of critical phenomena in complex systems.
