Ginzburg-Landau theory for skyrmions in inversion-symmetric magnets with competing interactions
Shi-Zeng Lin, Satoru Hayami
Magnetic skyrmions have attracted considerable attention recently for their huge potential in spintronic applications. Generally skyrmions are big compared to the atomic lattice co…
Vortex Crystals with Chiral Stripes in Itinerant Magnets
Ryo Ozawa, Satoru Hayami, Kipton Barros +3
We study noncoplanar magnetic ordering in frustrated itinerant magnets. For a family of Kondo square lattice models with classical local moments, we find that a double- noncopla…
Asymmetric Magnon Excitation by Spontaneous Toroidal Ordering
Satoru Hayami, Hiroaki Kusunose, Yukitoshi Motome
Effects of spontaneous toroidal ordering on magnetic excitation are theoretically investigated for a localized spin model that includes a staggered Dzyaloshinsky-Moriya interaction…
Spontaneous multipole ordering by local parity mixing
Satoru Hayami, Hiroaki Kusunose, Yukitoshi Motome
Broken spatial inversion symmetry in spin-orbital coupled systems leads to a mixing between orbitals with different parity, which results in unusual electronic structures and trans…
