Abstract:	Large exchange bias effects (ΔE 1. 1 erg/cm2) were observed in antiferromagnetic (FeF2)-ferromagnetic (Fe) bilayers grown on MgO. The FeF2 grows along the spin-compensated (110) direction. The FeF2-Fe interface roughness was characterized using specular and diffuse x-ray diffraction and atomic force microscopy. The magnitude of the exchange bias field H E increases as the interface roughness decreases. These results imply that magnetic domain creation in the antiferromagnet plays an important role.
