  We study the reversal of magnetization in an isotropic ferromagnetic film
free from charges by exposing it to a circularly polarized electromagnetic (EM)
field. The magnetization excitations obtained in the form of line and lump
solitons of the completely integrable modified KP-II equation which is derived
using a reductive perturbation method from the set of coupled Landau-Lifshitz
and Maxwell equations. It is observed that when the polarization of the
EM-field is reversed followed by a rotation, for every $ {\pi \over 2}
$-degrees, the magnetization is reversed.
