Ultrafast switching in Mn₃Sn antiferromagnets for non-volatile magnetic memory and logic spintronic devices

"electrically driven switching without substantial heating and under a weak current... switching completing within few to several tens of ps... fastest was 140 ps, constrained by the short current pulses that could be generated by the current device setup, not by the material itself... faster computing, communications, and advanced electronics,,, future: switch even faster under optimized conditions, including creating even shorter current pulses"
