Figure 5
(a) Net magnetization vectors for slices to the left- and to the right-hand side of the APB (large black triangles) together with the individual spin vectors (small triangles) for 9.2 nm particles. (b) A sketch of a particle with D ≃ 9 nm, showing the numbered slices. The slab positions indicated at the top of panel (a) correspond to the slice numbers shown in (b). The canting of spins is confined to the region within one unit cell around the APB, and this is indicated in an exaggerated way by the arrows below the particle shown in panel (b). |
