Abstract
At the surface of a magnetic fluid, parametric waves can be excited by an alternating magnetic field, parallel to the surface. With this ani sotropic system, Fee observe a pattern transition from parallel rolls, perpendicular to the magnetic field, to a rectangular array of cross rolls. The neutral curve of the transition is well explained by a mode l of four coupled Landau-Ginzburg equations.
