摘要：
Magnetic thin film wires with perpendicular magnetic anisotropy (PMA) containing domain walls (DWs) have been proposed for magnetic logic and memory devices. Using micromagnetic simulations, the magnetic configuration of a DW as a function of the magnitude of the PMA, wire width and thickness is described, showing the regimes of stability of Bloch and Neel walls. Stray field leads to repulsive interactions preventing the formation of 360 degree DWs, and promote uniform spacing between multiple DWs confined within a nanowire.
