Visible light-induced magnetization change of the cyano-bridged 3d-4f heterobimetallic

A visible light-induced magnetization change of the 3d-4f heterometallic, [Nd(DMF)(4)(H2O)(3)(mu-NC)Co(CN)(5)] (.) H2O (DNIF = N,N-dimethylformamide), is observed and described. The plots of (chiM) T versus T of the complex showed that the T values, after visible light illumination, were enhanced by about 25% as compared to before irradiation in the temperature range of 5-40 K.
