Driving Skyrmions in a Composite Bilayer
arXiv:1606.04595 · doi:10.1103/PhysRevB.94.014311
Abstract
Magnetic Skyrmions and multiferroics are the most interesting objects in nanostructure science that have great potential in future spin-electronic technology. The study of multiferroic Skyrmions has attracted much interest in recent years. This article reports magnetic Bloch Skyrmions induced by an electric driving field in a composite bilayer (chiral-magnetic/ferroelectric bilayer) lattice. By using the spin dynamics method, we use a classical magnetic spin model and an electric pseudospin model, which are coupled by a strong magnetoelectric coupling in the dynamical simulations. Interestingly, we observe some skyrmion-like objects in the electric component either during the switching process or by applying a magnetic field, which is due to the connection between the electric and the magnetic structures.
