The coexistence of ferromagnetism and chirality broadens the fundamental physical properties of chiral materials; however, organic chiral materials exhibiting ferromagnetism are still limited. Here, we fabricate organic chiral ferromagnets, where left-handed and right-handed organic chiral ferromagnets present a giant difference in saturation magnetization and coercivity. Such behavior can be attributed mainly to the helical arrangement of molecules generating orbital angular momentum. The chirality generates orbital angular momentum, acting as a key intermediate, and induces an interaction between the polarized spin and photon to realize spin-chiroptical coupling, where a series of circularly polarized transmissivity-magnetic field (T-H) loops is induced.

铁磁性和手性的共存拓宽了手性材料的基本物理性质；然而，表现出铁磁性的有机手性材料仍然有限。在这里，我们制造了有机手性铁磁体，其中左旋和右旋有机手性铁磁体在饱和磁化强度和矫顽力方面存在巨大差异。这种行为主要归因于产生轨道角动量的分子的螺旋排列。手性产生轨道角动量，作为关键中间体，并诱导极化自旋和光子之间的相互作用以实现自旋 - 手性耦合，其中诱导出一系列圆极化透射率 - 磁场（TH）回路。
