Magnetic vortex-antivortex crystals generated by spin-polarized current

We study vortex pattern formation in thin ferromagnetic films under the action of strong spin-polarized currents. Considering the currents which are polarized along the normal of the film plane, we determine the critical current above which the film goes to a saturated state with all magnetic moments being perpendicular to…

Bloch Point Structure in a Magnetic Nanosphere

We classify possible types of Bloch points and analytically derive the shape of the magnetization distribution for different Bloch points. Phys. Rev. B 85, 224401 (2012), 10.1103/PhysRevB.85.224401, PDF. Supplementary materials.
