Mixed-valance manganites with strong electron correlation exhibit strong potential for spintronics, where emergent magnetic behaviors, such as propagation of high-frequency spin waves and giant topological hall effects can be driven by their mesoscale spin textures. here, we create magnetic vortex clusters with flux closure spin configurations in single-crystal la0.67sr0.33mno3 wire. a distinctive transformation from out-of-plane domains to a vortex state is directly visualized using magnetic...Mixed-valance manganites with strong electron correlation exhibit strong potential for spintronics, where emergent magnetic behaviors, such as propagation of high-frequency spin waves and giant topological hall effects can be driven by their mesoscale spin textures. here, we create magnetic vortex clusters with flux closure spin configurations in single-crystal la0.67sr0.33mno3 wire. a distinctive transformation from out-of-plane domains to a vortex state is directly visualized using magnetic force microscopy at 4 k in wires when the width is below 1.0 mu m. the phase-field modeling indicates that the inhomogeneous strain, accompanying with shape anisotropy, plays a key role for stabilizing the flux-closure spin structure. this work offers a new perspective for understanding and manipulating the non-trivial spin textures in strongly correlated systems.» weiterlesen» einklappen
