Non-circular skyrmion and its anisotropic response in thin films of chiral magnets under tilted magnetic field
arXiv:1508.06361 · doi:10.1103/PhysRevB.92.180401
Abstract
We study the equilibrium and dynamical properties of skyrmions in thin films of chiral magnets with oblique magnetic field. The shape of an individual skyrmion is non-circular and the skyrmion density decreases with the tilt angle from the normal of films. As a result, the interaction between two skyrmions depends on the relative angle between them in addition to their separation. The triangular lattice of skyrmions under a perpendicular magnetic field is distorted into a centered rectangular lattice for a tilted magnetic field. For a low skyrmion density, skyrmions form a chain like structure. The dynamical response of the non-circular skyrmions depends on the direction of external currents.
