The interaction of magnetoplasma waves and spin waves in bulk ferromagnetic materials has been investigated for the case in which the direction of propagation is perpendicular to the static magnetic induction. For this geometry there are two types of magnetoplasma waves, but only one of them interacts with the spin waves. This one is a transverse plasma wave that propagates at frequencies above the plasma frequency. At wave numbers for which the interaction is a maximum, the modes cannot be identified as pure plasma or pure spin waves. The interaction can only be observed in materials in which the plasma frequency is less than the cyclotron frequency. Therefore, the interaction cannot be seen in metals, but it might be possible to obtain the interaction in a ferromagnetic semiconductor.
