A series of measurements were performed in order to analyze the impact of including an additional metal (known to have a Spin Hall effect) directly below another metal with the opposite sign of the effect. Experimental data shows, at first glance, that there is an anomalous enhancement of the spin Hall angle when this extra metal layer is included. The effect was noted by observing the switching current density for several samples. Each sample with a thicker underlayer of this metal, exhibited less current density for switching, thus opening the opportunity for enhancement of the spin Hall effect through the placement of an extra underlayer of metal featuring a spin Hall effect.
