Propagation, Dispersion, and Attenuation of Backward-Traveling Magnetostatic Waves in Yig

Magnonic Holographic Memory

“…In contrast to optical waves, spin waves are characterized by relatively slow group velocity (e.g. about 10 5 -10 8 cm/s 11,12 ) and short decay time (e.g. about 10…”

“…-9 -10 -6 s at room temperature 12 ). These technological characteristics have left many to ignore spin waves as information carriers in the past.…”
