中文摘要	We have grown 100-nm-thick epitaxial Fe3O4(111) film on alpha-Al2O3(0001) substrate at room temperature by the laser molecule beam epitaxy method. Exchange bias effect is observed once the film is cooled from 300 K to 5 K in the presence of a magnetic field, characterized by the shift and expansion of magnetic hysteresis loops. The observed exchange bias effect is related to the exchange coupling between antiferromagnetic Fe-O-Fe superexchange interactions at antiphase domain boundaries and ferromagnetic spins in the neighboring Fe3O4 domains. The magnitudes of the exchange bias field and coercive field show strong dependence on magnetic and thermal histories. (C) 2014 Elsevier Ltd. All rights reserved.
