Topological transition in spectrum of skyrmion crystal with uniaxial anisotropy
V. E. Timofeev, D. A. Bedyaev, D. N. Aristov
The band structure of elementary excitations of skyrmion crystal in thin ferromagnetic film with Dzyaloshinskii-Moriya interaction and uniaxial magnetic anisotropy under external m…
Magnon edge states of skyrmion crystal in non-uniform magnetic field
V. E. Timofeev, D. N. Aristov
A regular lattice of magnetic skyrmions is the ground state of thin ferromagnetic films with Dzyaloshinskii-Moriya interaction in a relatively wide range of external magnetic field…
Stability boundaries of the skyrmion phase in non-centrosymmetric ferromagnets with Dzyaloshinskii-Moriya interaction
S. V. Grigoriev, V. E. Timofeev, D. N. Aristov
Stability boundaries of the skyrmion lattice in non-centrosymmetric bulk ferromagnets with the Dzyaloshinskii-Moriya interaction in external magnetic field are discussed. We compar…
Goldstone mode of Skyrmion Crystal
V. E. Timofeev, D. N. Aristov
We discuss the Goldstone mode of skyrmion crystal in a model of two-dimenssional ferromagnet with Dzyaloshinskii-Moriya interaction in magnetic field. We use stereographic projecti…
