From: Plasmonic layer-selective all-optical switching of magnetization with nanometer resolution
Polarization-dependent all-optical switching of magnetization in different layers of the heterostructure. Background-corrected magneto-optical images are shown, taken after exposing the heterostructure to a single p-polarized (left spot) and s-polarized (right spot) optical pulse, incident at an angle of 59°. Also shown is a cross-section (averaged over a width of 1.8 µm) extracted from the image. The left (right) arrow indicates the orientation of the magnetization of Gd within the top (bottom) layer of GdFeCo. The results shown in a and b were obtained with an incident fluence of ∼10 mJ/cm2 and ∼12 mJ/cm2 respectively
