dc.description.resumo	We study the magnetic phases of a thin helimagnetic film, with the c axis along the normal to the surface, in the presence of a dc external field H parallel to the c axis. For small values of H we have found a conical phase, as in the bulk, with small modifications near the surfaces. This surface modified conical phase collapses into a planar structure, the c-fan phase, when H is greater than a threshold value H*. The c-fan phase consists of a magnetic pattern in which the magnetic moments are in a plane perpendicular to the surface, containing one of the easy directions of the basal plane. We show that the c-fan phase does not form in the bulk and present results for a Dy thin film near the Ne`el temperature.	pt_BR
