“…From this point, fcc-Co (111) or hcp-Co (0001) based materials are promising candidates, since a large interfacial PMA can easily be obtained for the Co (111) based multilayers. To date, several studies have reported on the electric field effect of Co (111) based multilayer systems, for example, electric field effect on Curie temperature of Co, 12) magnetic anisotropy of the induced moment of Pd in the Co/ Pd/MgO structure, [13][14][15][16] and magnetic anisotropy of Co in the Pt/Co/MgO structure, [17][18][19] SrTiO 3 /Co/Pt structure, 20) and Co/CoO/MgO oxidized interface. 21) A VCMA coefficient of up to 230 fJ V -1 m -1 has been reported at room temperature.…”
