(a) Dependences of Hs on thickness of Fe film of Fe/Si (557) film in the temperature range of 90 K–300 K, with the inset showing the plots of Hs versus 1/dFe at different temperatures. The dotted lines and solid lines are the experimental results and fitting results, respectively. (b) Temperature dependences of and obtained from the fitting results for dFe < 32 ML, with the inset showing the in-situ Kerr loops perpendicular to the step for dFe = 13.5 ML for temperatures of 300 K and 90 K. (c) Fe film thickness dependences of obtained by setting the values from panel (b) in the temperature range of 90 K to 300 K. (d) Thickness and temperature dependences of Hs obtained based on the experimental results and fitted anisotropy fields.
