Evidence of the exchange coupling in the Co/α-Fe2O3 system
2008
The magnetic exchange coupling in Co/α-Fe2O3(0001) interfaces has been studied. In this paper, we investigated magnetic properties at macroscopic (hysteresis loops) and microscopic (magnetic domain structure) scales. The system shows increased coercive fields and magnetic domain duplication likely mediated by the presence of a metallic interfacial Fe layer.
