Phys.org November 11, 2022 Skyrmions and bimerons are versatile topological spin textures that can be used as information bits for both classical and quantum computing. An international team of researchers (Japan, China, Australia) has demonstrated the creation of isolated skyrmions and their subsequent transformation to bimerons by harnessing the electric current-induced Oersted field and temperature-induced perpendicular magnetic anisotropy variation. The reversible transformation between skyrmions and bimerons was controlled by the current amplitude and scanning direction. Both skyrmions and bimerons could be created in the same system through the skyrmion-bimeron transformation and magnetization switching. Deformed skyrmion bubbles and chiral labyrinth domains […]

The long-range transport of deconfined magnetic hedgehogs
Phys.org January 18, 2021 Using magnetic insulators to achieve long-range transport of spins has proved highly challenging. Researchers at UCLA resorted to topological spin textures rather than spins themselves for the purpose of long-range transport. The magnetic hedgehog is one type of topologically protected spin texture that generically exits in three-dimensional magnets. The researchers showed that the hedgehog current is a well conserved quantity and can be explored to achieve long-range transport in magnetic insulators. The study is based on the theoretical construct topological conservation law, which allowed the researchers to leverage the idea of hydrodynamics of topological spin textures. […]
