Fig. 3: Time-resolved MOKE signal of Co single layer.
From: Laser-induced coherent spin change due to spin-orbit coupling
a Normalized magnetization-dependent Kerr rotation \(/{{\rm{\theta }}}_{{\rm{Static}}}\) and normalized reflectance \(/{\rm{R}}\). Blue circle (black triangle) symbols are \(/{{\rm{\theta }}}_{{\rm{Static}}}\) obtained with laser fluence of 2.5 mJ cm−2 (4.5 mJ cm−2). Red dotted curve is \(\Delta {\rm{R}}/{\rm{R}}\). A blue (black) arrow indicates a transient peak signal of \(\Delta {{\rm{\theta }}}_{{\rm{Kerr}}}/{{\rm{\theta }}}_{{\rm{Static}}}\). A red arrow indicates a transient peak signal of \(\Delta {\rm{R}}/{\rm{R}}\). b Calculated time evolution of \(\left\langle \delta S\right\rangle\) and \(\left\langle \delta L\right\rangle\) for a Co single layer (10 ML).
