Interplay between tetragonal magnetic order, stripe magnetism, and superconductivity in iron-based materials
Jian Kang, Xiaoyu Wang, A. V. Chubukov +1
Motivated by recent experiments in BaKFeAs {[}A. E. Böhmer \textit{et al}, to be published{]}, we analyze the type of spin-density wave (SDW) order in dop…
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…
Magnetic order without tetragonal-symmetry-breaking in iron arsenides: microscopic mechanism and spin-wave spectrum
Xiaoyu Wang, Jian Kang, Rafael M. Fernandes
Most iron-based superconductors undergo a transition to a magnetically ordered state characterized by staggered stripes of parallel spins. With ordering vectors or ,…
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…
Manipulation of gap nodes by uniaxial strain in iron-based superconductors
Jian Kang, Alexander F. Kemper, Rafael M. Fernandes
In the iron pnictides and chalcogenides, multiple orbitals participate in the superconducting state, enabling different gap structures to be realized in distinct materials. Here we…
