Magnetism and magnetoelectric coupling properties of TCCTs. a) Electric field tuning of magnetization of TCCTs under dark and photoexcitation conditions at different electric field. The light intensity is 70 mW cm−2. b) The orientations related to ferromeagnetism and paramagnetism by projecting the structure of C60 molecules along 010 direction created by PyMOL.[48] The 6–6 double bonds in upper layer are colored in red. c) The configurations of charge and spin in TCCTs. The interactions between molecules are presented as 1D chain. Purple circles, shaded yellow ovals, gray arrows, and purple arrows represent molecules, electron distributions, electric dipoles, and spins, respectively, d) The loading of electric field along the chain direction with the enhancement of both polarization and magnetization.
