摘要：

The contrast mechanism in spin-polarized scanning tunneling spectroscopy (SP-STS) is demonstrated on perpendicularly magnetized Fe nanowires grown on stepped W(110). By using Gd-coated tips, the antiferromagnetic domain structure of the nanowires can be imaged. The influence of an external magnetic field on the nanowire domain structure is demonstrated. It is shown that the antiferromagnetic domain structure of the Fe nanowires depends strongly on the miscut of the W(110) substrate. At high miscut the magnetization alternates between adjacent stripes, whereas at low miscut it alternates within the individual stripes.
