New Concept for Magnetization Switching by Ultrafast Acoustic Pulses
It is shown theoretically that a single a few picoseconds long acoustic pulse can reverse magnetization in a magneto-strictive material Terfenol-D. Following giant magneto-elastic changes of free energy density the magnetization vector is kicked out of a local in-plane energy mininum and decays into another minimum. For acoustic pulse duration …
