Controlling spin direction is the key for spintronic devices as it induces efficient and field-free switching. Herein, the authors propose using lattice vibrations in acoustic devices to replace the charge motion in conventional spintronic devices to realize the rotation of spin direction, that is, acoustic spin rotation. Acoustic spin rotation offers higher efficiency than spin rotation in conventional charge-current based spintronic devices.
