"faster, less heat... magnon quasiparticles representing collective excitation of spins, and phonon acoustic surface waves propagating along film... nano-structured surface acoustic wave resonator confining ultrasound waves to specific spot enhances shear sound waves allowing strong coupling in Co20Fe60B20 film at room temperature between surface sound waves and resonator's magnets... quantum possibilities at ultra-low temperatures"
