摘要：

Compositional dependency of all-optical light helicity-dependent magnetic switching (AO-HDS) in ferromagnetic GdFeCo alloy is presented. It is found that AO-HDS is associated with the collinear sub-lattice magnetization and not with the net magnetization. An explanation of the AO-HDS based on magnetic circular dichroism exactly matches the above features of experiments.
