Reversible Switching of Interlayer Exchange Coupling through Atomically Thin VO2 via Electronic State Modulation
Résumé
Spintronic interfaces (spinterfaces) with dramatically changeable electronic properties can be a magic building block in spintronics. In this work, we study the interlayer exchange coupling (IEC) effect in a synthetic magnetic multilayer system, where atomically thin phase-change material VO 2 is adopted as a spinterface with reversible metal-to-insulator transition. Repeatable switching from antiferromagnetic coupling to ferromagnetic coupling is observed in this multilayer system. As a proof-of-concept demonstration of interface-tailored spintronics, this work might provide a general strategy for beyond-CMOS electronics.
