Active Magnetoelectric Control of Terahertz Spin Current (original) (raw)

Active magnetoelectric control of terahertz spin current is explored in multiferroic spintronic devices, where piezoelectric strain manipulates spin currents through ferromagnetic and heavy metal layers. The research demonstrates that the effective magnetization can be controlled via electric fields, allowing for phase switching of emitted terahertz pulses. This novel control mechanism has significant implications for the development of advanced opto-spintronic devices for computing and communication technologies.
