The orbital angular momentum of a particle acts as an intermediary for magneto-optic coupling through spin-orbit-photon interactions. In this work, the spin-photon interactions in organic ferromagnetic crystals with negligible orbital angular momentum were studied, and photo-magnetic coupling generated through direct spin-photon interactions was observed. Additionally, it was demonstrated that spin angular momentum can be directly transferred from the polarized spin of an electron to a photon to alter the polarized state of light. Spin-photon interactions exhibit anisotropy in organic ferromagnets. Moreover, when the temperature was increased above the Curie temperature of organic ferromagnets, spontaneous spin polarization was not generated, which resulted in the disappearance of photo-magnetic coupling.
