CoFeB/MgO/CoFeB structures with orthogonal easy axes: perpendicular anisotropy and damping

H. Głowiński, A. Żywczak, J. Wrona +4

We report on the Gilbert damping parameter $\alpha$, the effective magnetization $4\pi M_{eff}$, and the asymmetry of the $g$-factor in bottom-CoFeB(0.93~nm)/MgO(0.90--1.25~nm)/CoFeB(1.31~…
