(a) Transmission spectrum of 20 nm-thick Co thin film. (b) Magnetic field dependence of normalized complex Kerr rotation in longitudinal configuration (L-MOKE curve) for 20 nm-thick Co thin film. (c) Magnetic field dependence of normalized Kerr ellipticity in polar configuration (P-MOKE curve) for the Co thin film with two different incident wavelengths (λ): 500 nm (red circles and line) and 750 nm (blue hollow squares and line).
