Abstract
<jats:title>Abstract</jats:title><jats:p>The emergence of spin‐orbit torques as a promising approach to energy‐efficient magnetic switching has generated large interest in material systems with easily and fully tunable spin‐orbit torques. Here, current‐induced spin‐orbit torques in VO<jats:sub>2</jats:sub>/NiFe heterostructures are investigated using spin‐torque ferromagnetic resonance, where the VO<jats:sub>2</jats:sub> layer undergoes a prominent insulator‐metal transition. A roughly twofold increase in the Gilbert damping parameter, α, with temperature is attributed to the change in the VO<jats:sub>2</jats:sub>/NiFe interface spin absorption across the VO<jats:sub>2</jats:sub> phase transition. More remarkably, a large modulation (±100%) and a sign change of the current‐induced spin‐orbit torque across the VO<jats:sub>2</jats:sub> phase transition suggest two competing spin‐orbit torque generating mechanisms. The bulk spin Hall effect in metallic VO<jats:sub>2</jats:sub>, corroborated by the first‐principles calculation of the spin Hall conductivity , is verified as the main source of the spin‐orbit torque in the metallic phase. The self‐induced/anomalous torque in NiFe, with opposite sign and a similar magnitude to the bulk spin Hall effect in metallic VO<jats:sub>2</jats:sub>, can be the other competing mechanism that dominates as temperature decreases. For applications, the strong tunability of the torque strength and direction opens a new route to tailor spin‐orbit torques of materials that undergo phase transitions for new device functionalities.</jats:p>
