Magnetic skyrmions are small whirling topological defects in a texture magnetization state. Their stabilization and dynamics depend strongly on their topological properties. Skyrmions are induced by non-centrosymmetric crystal structure of magnetic compo
In the physics literature, the inability to continuously deform a topologically non-trivial skyrmion configuration into the topologically trivial uniform ferromagnetic state is often referred to astopological protectionof magnetic skyrmions [36]. We note that this is somewhat of a misnomer, as a topolog...

Magnetic skyrmions, the topological spin textures firstly observed in chiral magnets, have aroused huge interest due to their emergent electromagnetism and
Nanoscale magnetic skyrmions in metallic films and multilayers: a new twist for spintronics Magnetic skyrmions are chiral quasiparticles that show promise for the transportation and storage of information. On a fundamental level, skyrmions are model systems for topologically protected spin textures and can...
Two aspects of issues need to be prepared in our scenario. On one hand, the sample design, such as the magnetic multilayers with moderate perpendicular magnetic anisotropy (PMA), interfacial DMI, and film thickness play a significant role on the generation of magnetic skyrmions43. Here, the Co...
When two magnetic skyrmions – whirl-like, topologically protected quasiparticles – form a bound pair, a biskyrmion state with a topological charge of NSk = ±2 is constituted. Recently, especially the case of two partially overlapping skyrmions h
