CoFeB／Pt多层膜的垂直磁各向异性研究
Perpendicular magnetic anisotropy in the CoFeB/Pt multilayers by anomalous Hall effect
摘要
Abstract
The perpendicular magnetic anisotropy （PMA） in as-deposited [CoFeB/Pt]n multilayer is studied by using anomalous Hall effect. A clear PMA is observed in the ultrathin （- 0.5 nm） amorphous CoFeB layer sandwiched by Pt. The PMA in as-deposited [CoFeB/Pt]n multilayers is strongly dependent on the thicknesses of CoFeB, Pt, and the number of CoFeB/Pt bilayers. With the increase of the number of CoFeB/Pt bilayers （n ≥ 5）, the hysteresis loop changes from rectangular to bow-tie shaped, and then the net moment approaches to zero in the remnant state. Moreover, the coercivty of [CoFeB/Pt]n multilayers is much low, which meets the requirement for free perpendicular electrode in the future spintronic device.关键词
