Rezumat

We present a new microscopic approach for the description of the effects of an external direct current (dc) electric field on the magnetic, polarizability, and spectroscopic characteristics of molecular crystals containing cyanide-bridged Fe–Co clusters as structural units. In addition to the interaction with the electric field, the model allows for metal–metal electron transfer, intracluster magnetic exchange, and long-range electron-deformational interactions, which are taken into account within the mean-field approach. The external electric field gives a unique possibility to manipulate the polarizability, magnetic, and spectroscopic characteristics of cyanide-bridged Fe–Co clusters.
