铁磁和反铁磁自组装单层膜界面的交换耦合效应增强了磁性纳米颗粒的矫顽力。利用蒸发驱动自组装技术，将反铁磁Co3O4纳米立方体逐层有序地堆叠在铁磁Fe3O4纳米立方体上。铁磁性和反铁磁性纳米立方体的有序排列对增强铁磁性是有效的。
The coercivity of magnetic nanoparticles is enhanced by the exchange coupling effect at the interface of ferrimagnetic and antiferromagnetic self-assembled monolayers. Antiferromagnetic Co3O4 nanocubes were regularly stacked on an ordered monolayer of ferrimagnetic Fe3O4 nanocubes by layer-by-layer manipulation using evaporation-driven self-assembly. The ordered arrangements of the ferrimagnetic and antiferromagnetic nanocubes are effective for the enhancement of the ferromagnetic character.
