The organic magnetoelectric complexes are beneficial for the development on flexible magnetoelectric devices in the future. In this work, we fabricated all organic multiferroic ferromagnetic/ferroelectric complexes to study magnetoelectric coupling at room temperature. Under the stimulus of external magnetic field, the localization of charge inside organic ferromagnets will be enhanced to affect spin–dipole interaction at organic multiferroic interfaces, where overall ferroelectric polarization is tuned to present an organic magnetoelectric coupling. Moreover, the magnetoelectric coupling of the organic ferromagnetic/ferroelectric complex is tightly dependent on incident light intensity. Decreasing light intensity, the dominated interfacial interaction will switch from spin–dipole to dipole–dipole interaction, which leads to the magnetoelectric coefficient changing from positive to negative in organic multiferroic magnetoelectric complexes.

具有强界面自旋偶极相互作用的所有有机多铁磁电配合物

有机磁电配合物有利于未来柔性磁电器件的发展。在这项工作中,我们制造了所有有机多铁性铁磁/铁电配合物,以研究室温下的磁电耦合。在外部磁场的刺激下,有机铁磁体内部电荷的定域性将增强,从而影响有机多铁性界面处的自旋-偶极相互作用,其中整体铁电极化被调整为呈现有机磁电耦合。此外,有机铁磁/铁电复合物的磁电耦合紧密依赖于入射光强度。降低光强,主导的界面相互作用将从自旋-偶极相互作用转变为偶极-偶极相互作用,
