Extended Data Fig. 6: MOKE images obtained after irradiation of a fs-laser pulse for tCu = 10 nm without the reference layer.
From: Optically induced ultrafast magnetization switching in ferromagnetic spin valves

The incident laser fluence is 4.1mJ/cm2.The color scale indicates the magnetic configurations. A sketch shows the excitation (fs laser pulse)/probing (LED) geometries.
