Abstract
AbstractThe magnetic structure and the electronic transport properties of domain walls (DWs) in magnetic transition metal nanocontacts Ni, Co, and Fe are investigated from first principles. In particular, the shape of the DW pinned in a monatomic nanowire, which is suspended between two semi‐infinite leads, and the effect on the magnetotransport are discussed in detail. For the calculation, a modification of the Korringa–Kohn–Rostoker (KKR) method is used to treat noncollinear magnetic systems fully self‐consistently. It is shown that the DW profile differs from the known Bloch and Néel walls.
