摘要：

We demonstrate light-induced switching of the coercive field of true nano-stabilized Au:Fe nanoparticles with exceptionally good magneto-optical response. Two separate processes are identified, both exploitable for photocommutation. This innovative material allows combining appealing photoswitching properties with the advantages of traditional metallic nanoparticles, opening the way to new multifunctional nanostructures.
