"laser controlled collective electron spin magnetic vibration optical excitations (magnons) enabling information THz transmission/ storage... drives high-frequency magnon pairs via laser pulses, changing other magnons' frequencies (electronic transitions, lattice vibrations, magnetic excitations)/ amplitudes, thus magnetic properties in non-thermal way... effects caused by light, not laser excitation nor temperature, fast data transmission without heat slowing it down... also, research quantum effects at room-temperature"
