Figure 5: Laser power dependence of the temperature difference of the leads in the MTJ.
From: Giant spin-dependent thermoelectric effect in magnetic tunnel junctions

(a) Temperatures of the bottom lead (solid squares) and the top lead (open circles) as the bottom lead was heated for various laser powers. (b) Laser power dependence of the temperature difference between the bottom and the top leads. The error bars of the temperature difference are given by repeating the measurements.
