Field-Free Spin-Orbit Torque Switching of Canted van der Waals Magnets.

ABSTRACT: Spin-orbit torque (SOT) magnetization switching is crucial for next-generation energy-efficient spintronic technologies. The recent discovery of van der Waals (vdW) magnets holds promise for such SOT phenomena because of their tunable magnetic properties. However, a demonstration of energy-efficient and field-free SOT switching of vdW magnets is required for their potential applications. Here, we demonstrate field-free and deterministic switching using an intrinsic canted vdW magnet Fe₅GeTe₂ in a heterostructure with Pt having a larger spin Hall conductivity up to room temperature. Using anomalous Hall electrical detection for magnetization readout, we reveal that field-free deterministic SOT switching in the Fe₅GeTe₂/Pt Hall devices can be attri
