| (a) MFM of a representative Landau pattern under application of static external magnetic fields (green arrows) along a diagonal of the square. (b) Vortex resonance frequency for quasistatically increasing external field at different temperatures. (c) Dependency of the resonance frequency on the magnetic field as well as on Hext/MS and Hext/fr(0) for all three temperatures. |
