摘要：
The perpendicular magnetic anisotropy (PMA) and dynamic magnetization reversal process of Tb/CoFeB multilayers have been investigated. The PMA was established near the magnetization compensation point by the antiferromagnetic coupling between Tb and CoFeB layers. By controlling the repetitionnof multilayers of CoFeB/Tb, the PMA can be optimized accompanying the change of domain structure due to the different pinning. CoFeB/Tb ferrimagnetic multilayers with PMA could be used to improve spin-orbit torque efficiency and velocity of domain wall motion in spintronic devices.
