Schneiderin memoriam Franz Ulrich Hillebrecht,† 08/08/2006to his wife and children in deep compassion for the great lossiiiAbstractIn this thesis, the magnetic proximity effect (MPE) in highly-ordered transi-tion metal oxide (TMO) heterosystems composed of single crystals of ferrimag-netic (FIM) Fe O and thin antiferromagnetic (AF) NiO layers has been inves-3 4tigated by Photoelectron Emission Microscopy using polarized soft x-rays (X-PEEM). The systems have been prepared in-situ by Molecular Beam Epitaxyon single crystalline Fe O substrates polished to various crystallographic sur-3 4face orientations and conditioned by Ar sputtering and annealing in O back-2ground. The magnetic order was determined by vectorial magnetometry exploit-ing XMCD and anisotropic XMLD for single crystalline systems of cubic symme-try.
