Abstract
The magnetostatic modes of a ferromagnetic film including the uniform mode are absent when the spins are pinned and the exchange interaction is included. New modes, the magnetoexchange modes, occur with dispersion intermediate between the magnetostatic and exchange dispersions. Formulas and detailed results are presented for both the pinned cases. Experimental tests for deducing the effective boundary conditions are discussed.Keywords
