Transformation of a skyrmionium to a skyrmion through the thermal annihilation of the inner skyrmion

A Jiang, Y Zhou, X Zhang, M Mochizuki - Physical Review Research, 2024 - APS
Skyrmioniums are doughnutlike topological spin textures in chiral magnets, which are able
to move with zero skyrmion Hall effect. The annihilation of a skyrmionium involves the …
