Micromagnetic simulation of antiferromagnetic/ferromagnetic structures [PDF]
IEEE Transactions on Magnetics, 2002 A novel approach for solving the Landau-Lifshitz-Gilbert equation for antiferromagnets with the finite-element method is presented. The antiferromagnet is treated in a continuum theory which allows us to explore the domain structure on a mesoscopic length scale.

Micromagnetic simulation of Fe asymmetric nanorings
Journal of Magnetism and Magnetic Materials, 2012 During the last decade several methods to control the vortex chirality in nanodots have been proposed. One of them, the introduction of asymmetry in the geometry of the dots, originates interesting effects on the magnetic behavior of the particle.

Manipulating 1-dimensional skyrmion motion by the external magnetic field gradient
New Journal of Physics, 2020 We have investigated an approximated analytic form of the one-dimensional motion of skyrmions accelerated by a gradient of the external magnetic field. We find excellent agreement between the analytical calculations and micromagnetic simulations when the

Dynamic behavior of skyrmion collision: spiral and breath
New Journal of Physics, 2023 A magnetic skyrmion is a particle-like topological soliton, which is an ideal candidate for developing high-density storage and logic devices due to its nonvolatility and tunability.
