dc.description.abstractCo islands and films are characterized by x-ray magnetic circular dichroism photoemission electron microscopy. The spatial resolution capabilities of the technique together with atomic growth control permit obtaining perfectly flat triangular islands with a given thickness (3 ML), very close to an abrupt spin-reorientation transition. The magnetic domain configurations are found to depend on island size: while small islands can be magnetized in a single-domain state, larger islands show more complex patterns. Furthermore, the magnetization pattern of the larger islands presents a common chirality. By means of dichroic spectromicroscopy at the Co L absorption edges, an experimental estimate of the ratio of the spin and orbital magnetic moment for three monolayer thick films is obtained.

There is also an additional uncertainty in the degree of polarization of the x-ray beam. By measuring the XMCD of a thick Co film on W 110, not shown, we have obtained anomalously low magnetic-moment values. Although this affects the absolute values, the ratio is not modified. 26. B. T.

The x-ray beam moved visibly during the time needed to acquire the complete spectra. The motion along the short direction of the x-ray beam is corrected by moving the integration window to track the illuminated area. As a rough correction to the motion of the x-ray beam along the wide direction, we add a different constant intensity to each spectrum. Each constant is chosen to give both a flat background after the L absorption edge and similar intensity between absorption edges for both spectra. After that, we normalize them dividing by the intensity of the gold mesh to account for the photon energy dependence of the monocromator transmission. 31. S. Gallego private communication. 32. N.
