FeMn/Co/Cus001d films were epitaxially grown and investigated using photoemission electron microscopy and the surface magneto-optic Kerr effect. The FeMn antiferromagnetic order increases the Co film coercivity, switches the Co magnetization easy axis from the f110g direction to the f100g direction, and increases the Co film critical thickness at which the ferromagnetic transition occurs. The Neel temperature of the FeMn film increases with increasing FeMn film thickness. At room temperature, we constructed a magnetic phase diagram in the FeMnuCo thickness plane to describe the FeMn and Co magnetic phases.
