Phase reciprocity of spin-wave excitation by a microstrip antenna
Phase reciprocity of spin-wave excitation by a microstrip antenna
Using space-, time-, and phase-resolved Brillouin light-scattering spectroscopy we investigate the difference in phase of the two counterpropagating spin waves excited by the same microwave microstrip transducer. These studies are performed both for backward volume magnetostatic waves and magnetostatic surface waves in an in-plane magnetized yttrium iron garnet film. The …
