Photoinduced magnetization in a thin Fe–CN–Co film

The magnetization of a thin Fe–Co cyanide film has been investigated from 5 to 300 K and in fields up to 500 G. Upon illumination with visible light, the magnetization of the film rapidly increases. The original cluster glass behavior is further developed in the photoinduced state and shows substantial changes in critical temperature and freezing temperature. [Copyright &y& Elsevier]
