Abstract

A remarkable magnetic anisotropy field change up to 1572 Oe was achieved under a small operation voltage of 4 V through ionic liquid gating (ILG) control of spin reorientation transition (SRT) in Au/[DEME]+[TFSI]-/Pt/(Co/Pt)2/Ta heterostructures. The first principle calculation reveals that the ILG process influences the interfacial spin-orbital coupling introducing a net Rashba magnetic field, resulting in the modulation of SRT.
