Optical Visualization of the Spatial Distribution of the Intensity of Spin Waves in a Ferrite Film

摘要

A method and setup for visualizing the spatial distribution of the intensity of magnetostatic spin waves in ferrite films are described. The visualization method is based on local illumination of the film by focused optical radiation and the detection of the variation in the integral power of the wave. The intensity distributions of the surface spin waves in a ferrite-film waveguide are measured.
