In this work, room‐temperature organic chiral helical charge‐transfer ferromagnets are fabricated with a high thermal stability. Compared with achiral ferromagnets, involving chirality‐generated orbital angular momentum in chiral magnets will increase the value of magnetization. Under the stimulus of light, both right‐handed and left‐handed circularly polarized light can enhance the magnetization performance in chiral helical charge‐transfer magnets compared with linearly polarized light with an identical intensity. Moreover, the extinction ratio of transmission light can be tuned through applying an external magnetic field in this chiral helical system. Thus, it is expected that the organic chiral charge‐transfer magnets have enormous potential for the application of optical communication and polarized light detection.
