Figure 3

(a) Temperature dependence of the Kerr rotation at remanence for FeRh/(11 Å) Au/FeAu and FeRh/(50 Å) Au/FeAu. Arrows indicate heating and cooling branches (red and blue respectively). (b) The PMOKE loops collected for FeRh/(11 Å)Au/FeAu trilayers at 280 K during cooling (blue curve) and heating (red curve) process. The inset shows the LMOKE loop collected at 280 K during cooling process. (c) Dependence of the Kerr rotation at remanence as a function of the Kerr rotation at saturation with a linear fit marked by the dotted line. (d) The magnetic hysteresis loops collected for polar geometry at 300 K for FeRh/(11 Å) Au/FeAu and FeRh/(50 Å) Au/FeAu are shown. Insets show the zoomed central sections of these loops.
