| Abstract
| - Photoinduced magnetization has been recently evidenced by Hashimoto et al. in CoFe Prussianblue analogues. We synthesized three compounds with a variable cobalt environment to point out the conditionsrequired to observe the photoinduced magnetization. Structure and electronic structure of the compounds havebeen investigated combining XANES, infrared spectroscopy, and powder X-ray diffraction experiments.Magnetization as a function of temperature before and after irradiation showed that diamagnetic pairs CoIII−NC−FeII are necessary for the existence of the photoinduced magnetization, but their presence is not a sufficientcondition. The role of hexacyanoferrate vacancies in the phenomenon is pointed out.
