Abstract

Ionic liquid gating control of magnetic anisotropy in Au/[DEME]+[TFSI]-/Co/SiO2 multilayer structures was quantitatively determined by electron spin resonance method. A reproducible, reversible ferromagnetic resonance field shift of 219 Oe at an applied voltage of 1.5 V, with a large ME tunability of 146 Oe/V, was achieved at the room temperature. The large Voltage control of magnetic anisotropy change induced by the IL gating opens up a new door for highly effective voltage control of magnetism and related applications.
