Temperature dependence of the perpendicular magnetic anisotropy in Ta/Co sub(2)FeAl/MgO structures probed by Anomalous Hall Effect
We report a detailed study of the temperature dependence of the magnetic anisotropy in Ta/Co sub(2)FeAl/MgO structures by means of Anomalous Hall Effect measurements.

description | We report a detailed study of the temperature dependence of the magnetic anisotropy in Ta/Co sub(2)FeAl/MgO structures by means of Anomalous Hall Effect measurements. The volume magnetic anisotropy, although negligible at room temperature, shows a non-negligible value at low temperatures and favors an in-plane easy magnetization axis. The surface magnetic anisotropy, which promotes the perpendicular magnetic easy axis, shows an increase from 0.76 + or - 0.05 erg/cm super(2) at 300 K, up to 1.08 + or - 0.04 erg/cm super(2) at 5 K, attributed to the evolution of the Co sub(2)FeAl layer saturation magnetization with temperature. |
