Magnetic phases of fcc-like Fe films on Cu(001): answers from the spin-dependent electronic structure
In this paper the empty electronic structure of room temperature-grown fcc-like Fe films on Cu(001) is studied by spin-resolved inverse photoemission. For 6 monolayers, the magnetic exchange splitting of 0.9 eV of an sp-like surface state proves ferromagnetic order of the surface layer. The spin dependence of bulk-like states and the response to adsorbates reveal more than one, yet metastable ferromagnetic surface layers on top of nonferromagnetic layers. No indication of antiferromagnetic interlayer coupling was found at 90 K. Thinner films of 2.5 monolayers are completely in a stable ferromagnetic state with enhanced exchange splitting of the d states.
