a Temperature-dependent minor hysteresis loops by SQUID. Both Hup and Hdown are changed with the static temperature. b Extracted Hex and HC from (a) as a function of temperature. Hex decreases with the increase of the static temperature while HC stays unchanged within experimental error bars. c Temperature-dependent minor hysteresis loops by MOKE at a fixed pump fluence F of 2.40 mJ/cm2. As in (a), similar shifts of Hup and Hdown are shown. d Extracted Hex and HC from (c). The complementary magneto-optical method again confirms that a temperature increase of 80 K only affects Hex, but not HC. Error bars indicate the uncertainty in determining the displayed value from the experimentally measured data.
