"magnons' oscillation frequency controlled quasi instantly/ on demand by means of interacting: optical excitation, magnetic anisotropy (directional dependence), external magnetic field... scalable since material only 20 nm thick, so compatible with modern computer chip architecture... most cloud data is currently stored magnetically, but controlling frequency of spin waves (magnons) unlocks faster, energy-efficient data storage/ transfer"
