Figure 2
An enlargement of the spin structures of the 9.2 nm particles with an APB at the centre, indicated with a black rectangle. The structures were simulated under consideration of dipole–dipole interactions (visualized with MayaVi). A field of 5 T was applied along the vertical direction. Full parallel (octahedral sites) and antiparallel (tetrahedral sites) alignment with the applied field is shown with red and blue colours, respectively. Intermediate colours indicate spin canting away from perfect alignment. The introduction of an APB leads to a disturbance in the spin structure due to the antiferromagnetic exchange interaction across the boundary.
