Spin-Orbit Torque-Driven Magnetic Switching of Co/Pt-CoFeB Exchange Spring Ferromagnets
IEEE Transactions on Magnetics(2019)
摘要
We experimentally investigate spin-orbit torque (SOT) switching of a hybrid exchange spring system (ESS) in which a Co/Pt with perpendicular magnetic anisotropy (PMA) is coupled to a CoFeB thin film with an in-plane (IP) magnetic anisotropy (IMA). The magnetization tilt angle from the out-of-plane can be easily tuned by varying the thickness of the IMA layer due to the competition between PMA and ...
