Engineering Co/MgO interface with heavy metals for voltage-controlled magnetic anisotropy effect

We have investigated the voltage-controlled magnetic anisotropy (VCMA) effect in Co/MgO junctions by inserting a sub-atomic layer of heavy metals at the interface. We evaluated an electrical control of the magnetic anisotropy by using a micro-magneto-optical Kerr effect magnetometer. The VCMA coeffi...
