Sketch of the excitation (femtosecond-laser pulse)/probing (LED) geometries and MOKE images obtained after irradiation using a femtosecond-laser pulse starting from the P+ (red) and AP+ (blue) states for t Cu = 10 nm, with F = 3.7 and 5.9 mJ cm −2 . The colour scale indicates the magnetic configurations. Scale bar, 10 μm.
