摘要：

Magnetic wedges of Fe on Cu(100) are explored magneto-optically. In the region of 6-11 monolayers (ML) of fcc Fe grown at room temperature, in addition to a surface ferromagnetic layer with a Curie temperature approximately 250 K, the Fe bulk is antiferromagnetic with a Neel temperature of approximately 200 K. This fcc phase is stable only above a growth temperature of order approximately 200 K, below which the ferromagnetic spin-reorientation transition occurs at approximately 6 ML. The phase boundaries are delineated by cusps in the coercivity along the wedge.
