The simulation shows a 2D spin texture where tuning DMI strength and external magnetic field nucleates individual skyrmions and organizes them into a self-assembled hexagonal skyrmion lattice, or annihilates them back into a uniform field-polarized state.
Adjust the DMI-strength slider and the external-field slider to move through the helical, skyrmion-lattice, and field-polarized phases, watching skyrmions nucleate, pack into a triangular lattice, or annihilate in real time.
Sliders for Dzyaloshinskii-Moriya interaction strength and external magnetic field
Skyrmions can be dragged along a nanowire by electric current densities roughly a thousand times smaller than those needed to move a conventional magnetic domain wall, largely because of an efficient coupling called the emergent electromagnetic force between conduction electrons and the skyrmion's topological spin winding.
