Focusing on the propagation of orbital angular momentum in insulators, the thermally driven effects in the insulating orbital ferrimagnet CoMnO₃, which has net magnetization originating from orbital angular momentum, were investigated. Cr₂O₃/CoMnO₃/NM multilayers were fabricated, and structural, magnetic, and second-harmonic transverse voltage measurements were conducted. In the NM (Pt) layer sample, the hysteresis observed in the second-harmonic signal corresponds to the magnetization of CoMnO₃, suggesting the contribution of thermally driven orbital angular momentum propagation.
