Figure 4: Comparison of the Gilbert damping of Py films with different capping layers.
From: Experimental Investigation of Temperature-Dependent Gilbert Damping in Permalloy Thin Films

(a,b) Temperature dependence of the Gilbert damping of Py thin films with TaN capping layer (blue) and Al2O3 capping layer (green) for 5 nm Py and 30 nm Py, respectively. Error bars correspond to one standard deviation.
