Magnetization Reversal in Ferromagnetic Nanorings of Fourfold Symmetries

Figure 6

Phase diagrams simulated for nanorings with square corner cuts, assuming epitaxial anisotropy orientation along 0° (a), 45° (c), and random anisotropy axes (b). The colors of the texts correspond to those in Figure 5.
