Magnetic moments have been determined for the fct and bcc structural phases of Fe, stabilized on the (100) surface of Cu, from magnetic-circular-dichroism measurements. For the thin fct films, the spin and orbital moments are greatly increased to 3.4(7)μ_B and 0.24(5)μ_B, respectively. The larger moments found for the fct films scale with an increased energy shift in the position of the L₃ and L₂ absorption peaks. In addition, insight is gained into the energy governing the perpendicular anisotropy of the fct phase.
