22_36/2010Multifunctional Nanoparticles: Photocoercivity of Nano-Stabilized Au:Fe Superparamagnetic Nanoparticles (Adv. Mater. 36/2010)

Light-induced switching of the coercive field of Au:Fe nanoparticles with exceptionally good magneto-optical response is reported on p. 4054 by Lapo Bogani and co-workers. Two separate processes are identified, both of which are exploitable for photocommutation. This innovative material allows a combination of appealing photoswitching properties with the advantages of traditional metallic NPs, opening the way to new multifunctional nanostructures.
