Abstract
Two models of surface roughness are introduced in a transfer matrix approac h of spin wave resonance. A one-layer surface roughness is shown to lead in the case of a weak antiferromagnetic coupling to surface modes while an ex tended roughness leads to an effective unpinning with nonlinear contributio ns. Applications to multilayers are deduced. (C) 1999 Elsevier Science B.V. All rights reserved.
