Transport Theory of Metallic B20 Helimagnets
Jian Kang, Jiadong Zang
B20 compounds are a class of cubic helimagnets harboring nontrivial spin textures such as spin helices and skyrmions. It has been well understood that the Dzyaloshinskii-Moriya (DM…
Charged skyrmions on the surface of a topological insulator
Hilary M. Hurst, Dmitry K. Efimkin, Jiadong Zang +1
We consider the interplay between magnetic skyrmions in an insulating thin film and the Dirac surface states of a 3D topological insulator (TI), coupled by proximity effect. The ma…
Topological Charge Analysis of Ultrafast Single Skyrmion Creation
Gen Yin, Yufan Li, Lingyao Kong +3
Magnetic skyrmions are topologically non-trivial spin textures of potential interest for future information storage applications, and for such purposes, the control and understandi…
Universal Ratio of Intrinsic Resistivities of Spin Helix in B20 (Fe-Co)Si Magnets
S. X. Huang, Jian Kang, Fei Chen +6
The B20 magnets with the Dzyaloshinskii-Moriya (D-M) interaction exhibit spin helix and Skyrmion spin textures unattainable in traditional Heisenberg ferromagnets. We have determin…
Magnetoresistance due to Broken C4 Symmetry in Cubic B20 Chiral Magnets
S. X. Huang, Fei Chen, Jian Kang +4
The B20 chiral magnets with broken inversion symmetry and C4 rotation symmetry have attracted much attention. The broken inversion symmetry leads to the Dzyaloshinskii-Moriya that…
Electric field-induced Skyrmion distortion and giant lattice rotation in the magnetoelectric insulator Cu2OSeO3
J. S. White, K. Prša, P. Huang +9
Uniquely in Cu2OSeO3, the Skyrmions, which are topologically protected magnetic spin vortex-like objects, display a magnetoelectric coupling and can be manipulated by externally ap…
