摘要：

Exact calculations of eigenfrequencies and of eigenmodes magnetization profiles of spin waves in magnetic stripes are presented. We use an approach based on the finite elements method which takes a complete account of exchange and dipolar terms occurring in the equation of motion. The numerical results well agree with previously published experimental data concerning permalloy stripes. (C) 2003 Elsevier Science B.V. All rights reserved.
