Abstract: | Photoelectron emission microscopy in connection with magnetic circular dichroism in soft X-ray absorption can be used for
the microscopic imaging of magnetic domains in layered thin film structures consisting of several magnetic layers. Due to
the element-selectivity of the method, the different magnetic layers in such a structure can be imaged separately, provided
that they contain different elements. This has been applied for the investigation of Co/Cu/Ni trilayers, epitaxially grown
on Cu (001). The magnetic coupling between the Co and Ni layers can be directly visualized from comparing layer-resolved magnetic
domain images of both layers. As a consequence of the competition between the anisotropy energies of the two magnetic layers
and the magnetic coupling energy, spin-reorientation transitions between collinear and non-collinear magnetic configurations
are observed. Apart from this globally observable magnetic interlayer coupling a micromagnetic coupling mechanism is also
evident from the layer-resolved domain images. It is caused by magnetostatic interaction of local stray fields from domain
walls.
