The effect of thermal fluctuations on the phase structure of monoaxialhelimagnets with external magnetic field parallel to the chiral axis isanalyzed by means of a saddle point expansion of the free energy. The phasetransition that separates the conical and forced ferromagnetic phases ischanged to first order by the thermal fluctuations. In a purely monoaxialsystem the pitch of the conical state remains independent of temperature andmagnetic field, as in mean field theory, even when fluctuations are taken intoaccount. However, in presence of weak Dzyaloshinskii-Moriya interactions in theplane perpendicular to the chiral axis, thermal fluctuations induce adependence of the pitch on temperature and magnetic field. This may serve todetermine the nature of magnetic interactions in such systems.
