▲ [14a-A501-4] Imaging of caustic-like spin wave beams radiated from different waveguide widths using heterodyne detection
Keywords:Spin wave
Spin wave-based logic devices are widely investigated due to their promising technology with extended functionality and improved performance. Imaging the propagating spin waves in real-space is fascinating approach to characterize their properties. In this study, we investigated the caustic-like spin wave beams radiated from different waveguide widths. For this purpose, we developed a spatially-resolved optical heterodyne detection of propagating spin waves by using the polar Kerr effect.
