Abstract:
This study presents experimental evidence of the substantial modulation of ferromagnetism and spin–orbit torque (SOT) efficiency in a Ta/Pt/Co/Ta/In2Se3 heterostructure with perpendicular magnetic anisotropy through light irradiation. An increase in SOT efficiency of ∼20% and a reduction in critical switching current density of ∼52% were observed. The significant modulation primarily originates from the photostrictive effect of a van der Waals-layered ferroelectric In2Se3 layer, which is assisted by thermal effects under light irradiation. The present research provides a potential approach to modulating magnetism and SOT efficiency for energy-efficient spintronic devices.
