在这项研究中，我们研究了电场下的MgO/Co/Pt结构的垂直磁各向异性。MgO/Co叠层中的界面各向异性能的变化，在施加栅极电压时，确定通过使用传输测量技术。结果表明，在充分低于居里温度的温度下，Co层表面电子数的减少导致垂直各向异性能的增强。
In this study, we have investigated perpendicular magnetic anisotropy in a MgO/Co/Pt structure under an electric field. The change in the interface anisotropy energy in a MgO/Co stack upon the application of a gate voltage was determined by using a transport measurement technique. The result indicates that a decrease in the electron number at the surface of the Co layer leads to the enhancement of the perpendicular anisotropy energy at a temperature sufficiently lower than the Curie temperature.
