Magnetic vortex evolution in self-assembled La0.7Sr0.3MnO3 nanoislands under in-plane magnetic field
The magnetic vortex formation at room temperature and its evolution under in-plane magnetic field is studied in chemically grown self-assembled La0.7Sr0.3MnO3 nanoislands of less than 200 nm in width. We use variable field magnetic force microscopy and numerical simulations to confirm that the vorte...

| Summary: | The magnetic vortex formation at room temperature and its evolution under in-plane magnetic field is studied in chemically grown self-assembled La0.7Sr0.3MnO3 nanoislands of less than 200 nm in width. We use variable field magnetic force microscopy and numerical simulations to confirm that the vortex state is ubiquitous in these square-base pyramid shape epitaxial La0.7Sr0.3MnO3 nanostructures, and that it requires in-plane magnetic fields below 40 kA/m to be annihilated. |
