Magnetic skyrmionium information

Out-of-plane spin texture of a skyrmion and skyrmionium. Green colour represents spins that point out of the screen and yellow colour represents spins that point into the screen.

In magnetic systems, excitations can be found that are characterized by the orientation of the local magnetic moments of atomic cores. A magnetic skyrmionium is a ring-shaped topological spin texture and is closely related to the magnetic skyrmion.^[1]^[2]
