We show that the action of strong rapidly oscillating transverse magnetic field in easy-plane ferromagnet gives rise to the appearance of effective biaxial magnetic anisotropy and new soliton solutions in the form of Bloch and N\'eel domain walls. Exact analytical expressions describing the conversion of a N\'eel wall into the stationary Bloch wall under dissipation are derived on the ground of the adiabatic approximation which are in good agreement with the numerical simulations of the basic strongly perturbed Landau-Lifshitz equation.
