The study demonstrates that spin orbit torque (SOT) can be enhanced in hybrid systems composed of metal-oxide structures, potentially due to spin absorption at the interface between different layers. This finding suggests promising prospects for the development of efficient spin-orbitronic devices.
Spin orbit torque (SOT) is essential to magnetization modulation in various ferromagnet/non-magnet bilayers. In this study, we demonstrated that SOT can be enhanced in a hybrid system composed of a perovskite oxide NdNiO3 (NNO) and a Ni81Fe19/Pt bilayer. We also find that the SOT enhancement might be attributed to spin absorption at the interface between the NNO and Ni81Fe19 layers. Our findings suggest that metal-oxide hybrid structures can be promising systems for the development of efficient spin-orbitronic devices. Published under an exclusive license by AIP Publishing.
