Résumé:

It is shown that nonlinear electromagnetic short solitary waves can propagate in a ferromagnetic medium, perpendicular to the magnetization density. The dynamics of the modulation of the wave in one transverse dimension is governed by a (2+1)-dimensional generalization of the completely integrable sine-Gordon model. We exhibit the line-soliton solution and study its transverse stability both analytically and numerically.
