Magnon field effect transistor paves the way for energy-efficient computing in the post-Moore era
"nonvolatile, lateral structure 3-terminal, room temperature, energy efficient magnon transport control via gate voltage pulses... as transistors shrink/ higher speeds, heat generated increases substantially, mitigated by transmitting spin information without electron motion... also, can switch magnetic moments enabling information transmission/ storage... ferrimagnetic insulator layered on ferroelectric material with 3 platinum stripes patterned on magnetic layer serving as injector, gate, and detector, respectively... strong modulation"
