The magnetic vortex formation at room temperature and its evolution under in-plane magnetic field is studied in chemically grown self-assembledLa0.7Sr0.3MnO3 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-planemagnetic fields below 40 kA/m to be annihilated.
