Photomagnetic Co–Fe Prussian Blue Thin Films Fabricated by the Modified Langmuir–Blodgett Technique

Co–Fe Prussian blue thin films have been prepared by means of a modified Langmuir–Blodgett technique, in which the hybrid monolayer composed of amphiphiles and clay platelets plays a template role for the formation Co–Fe Prussian blue thin films. Photoinduced magnetization was observed in the thin films as observed in the bulk Co–Fe Prussian blue. To the best of our knowledge, this is the first example of successful formation of Co–Fe Prussian blue thin films, which possess the ordered structure and, in addition, exhibit photoinduced magnetization.
