摘要: Non-collinear magnetization textures provide a route to novel device concepts in spintronics. These applications require laterally confined non-collinear magnets (NCM). A crucial aspect for potential is how the spatial proximity between NCM and vacuum or another material impacts texture on nanoscale. We focus prototypical exchange-driven given by helical spin order of bilayer Fe Cu(111). Spin-polarized scanning tunnelling spectroscopy density functional theory reveal nanosize- proximity-driven modification electronic magnetic structure interfacial contact with ferromagnet vacuum. An intriguing non-collinearity local sample probed above its surface results. It direct consequence spinor nature states NCM. Our findings possible advanced control nanoscale confinement.
