摘要	Heterointerfaces between ferromagnetic and antiferromagnetic materials play an important role in the development and applications of magnetic and electronic devices. Here, atomic and electronic structures of two types of Fe3O4/FeO interfaces with different magnetic coupling modes have been investigated by combining advanced transmission electron microscopy and first -principles calculations. It is found that the Fe3O4/FeO (001) and Fe3O4/FeO (111) interfaces can be formed between FeO and Fe3O4 due to different phase transformations. The Fe3O4/FeO (111) interface is generally closer to the steady state. The electronic structure of both types of Fe3O4/FeO interfaces changes significantly, which leads to a metal -insulator transition of the Fe3O4 layer at the interfaces. The energy difference between the ferromagnetic and antiferromagnetic coupling states across the Fe3O4/FeO interfaces is very small, indicating that magnetic flip-flopping easily occurs in the Fe3O4/FeO system. The atomic magnetic moment of the interfacial Fe atoms at the Fe3O4/FeO (001) interface decreases by similar to 10% due to the preferentially occupied dxz and dyz orbitals, while that at the Fe3O4/FeO (111) interface remains almost unchanged. These findings suggest that the Fe3O4/FeO interfaces are susceptible to magnetic coupling transition and may find applications in low -power consumption magnetic and electronic devices.
