Abstract
The interaction between spin waves and Alfvén waves is investigated in bulk ferromagnetic metals. It is shown that the Alfvén wave will interact strongly with the spin-wave system. In the presence of the interaction, the modes can no longer be identified as pure Alfvén- or spin-wave modes. The wave number at which resonance occurs can be varied by changing the strength of the external dc field. The results are applied to iron, in which it is expected that this interaction can occur.Keywords
