We have succeeded in developing highly ordered magnetic vortices in dense arrays of microstructured magnets and in evaluating individual spin configuration by employing a high-precision spin-imaging technique. High-definition pictures reveal fundamental properties of the ordered vortices, such as stability and interaction of vortex chirality. We have also demonstrated control of the chirality with the use of a magnetic field gradient but without introducing geometric asymmetry in the magnet shape. A simple control mechanism is deduced from micromagnetic simulations. [ABSTRACT FROM AUTHOR] |
