Abstract
Exchange bias is found in the Fe/FexMn1−x/Cu(001) bilayer films. The coercivity Hc is enhanced at blocking temperature Tb for the films with composition x between 0.25 and 0.35, but not for those between 0.1 and 0.25. A simple model based on the discrepancy of the Néel temperature TN and Tb is proposed, which may reveal the physical origins of these two temperature points.
