Abstract
The magnetic and electronic properties of wedge-shaped Cr(001) ultrathin overlayers grown on an Fe(001) layer were investigated using the magneto-optical effect. Precise measurements of the thickness dependence of the saturation Kerr ellipticity at room temperature show clear oscillations caused by the antiferromagnetic order and/or the quantum size effect in the Cr layer. The short period, A ≈ 2 ML, was observed clearly for photon energy between 2.25 and 3.75 eV and was constant in this energy range. The long period oscillation observed from 3.25 to 4.75 eV changes its period.
