It is shown that in a lossless and in-plane saturated ferromagnetic film the dynamic permeability is negative for frequencies corresponding to the backward volume spin waves. The electromagnetic radiation can be coupled to that of backward spin waves and the ferromagnetic film behaves as a magnetic metamaterial with negative permeability.

Abstract

It is shown that in a lossless and in-plane saturated ferromagnetic film the dynamic permeability is negative for frequencies corresponding to the backward volume spin waves. The electromagnetic radiation can be coupled to that of backward spin waves and the ferromagnetic film behaves as a magnetic metamaterial with negative permeability.
