The PMOKE exemplary magnetic hysteresis loops measured for FeRh/(11 Å) Au/FeAu. (a) Loops measured at 340 K for polar and longitudinal (inset) geometries. (b) The temperature evolution of the PMOKE magnetic hysteresis loops collected during the cooling process across the FM ⇒ AFM transition. (c) The temperature dependence of PMOKE Kerr rotation at saturation (ROTSAT). Blue and red arrows indicate the cooling and heating branches respectively. (d) The magnetic hysteresis loop collected at 200 K in a narrower range of the external magnetic field.
