Abstract

Confined spin waves in single magnetic microstrips are investigated using a microwave photovoltage technique. Direct mapping of the spin wave evolution between surface, edge, and central modes is achieved by tuning the direction of the applied magnetic field. Both theoretical and numerical methods are used to study the evolution of the excitations and provide excellent agreement with the experimental results. The most prominent feature observed is a mode repulsing behavior which indicates mode hybridization in the dipole dominated part of the spin wave spectrum.
