The crystals of the organic semiconductor Cs2TCNQ3 have been successfully grown under strong external magnetic field, and their properties are compared with those of the crystals grown without magnetic field. The crystals grown under magnetic field higher than a certain temperature-dependent threshold field show remarkable change in electric, magnetic, and optical properties, despite no significant change in the crystal morphology and structure. Electric conductance data suggest the increasing of acceptors in the crystals grown under magnetic field, which is accompanied by the increasing of the Curie temperature by the amount of 100 K., and the intensification of the absorption band arises from inter-radical charge transfer transition. These results suggest that some newly electronic states have been induced by the applied field during the crystal growth.
