| Abstract: | Using sequential deposition methods, we have generated two different films of RbjCokFe(CN)6]l · nH2O for magneto-optical studies. The synthesis protocol was intentionally varied in order to generate samples with different degrees of surface homogeneity. As a consequence, film 1 possessed a powder-like rough surface, while film 2 was a smooth, quasi-two-dimensional film. Upon irradiation at 5 K with an external magnetic field of 200 G perpendicular to the film surface, the magnetization of film 1 increased, whereas the magnetization of film 2 decreased. This contrasting behavior is consistent with a dipolar field model describing the phenomena and is related to the novel anisotropy of the photoinduced magnetism in film 2, where the photoinduced magnetization increases or decreases depending on the orientation of the film with respect to the external field. |
