Anisotropic skyrmion crystal on a centrosymmetric square lattice under an in-plane magnetic field
Satoru Hayami
We investigate the instability toward a skyrmion crystal under an in-plane magnetic field in centrosymmetric tetragonal magnets. By performing the simulated annealing for a spin mo…
Rotational Response Induced by Electric Toroidal Dipole
Akimitsu Kirikoshi, Satoru Hayami
A ferroaxial ordering, which appears without mirror symmetry parallel to an electric axial moment, is described by a ferroic alignment of the electric toroidal (ET) dipole rather t…
Three-sublattice antiferro-type and ferri-type skyrmion crystals in centrosymmetric magnets
Satoru Hayami
We numerically investigate the stability of the skyrmion crystals in a centrosymmetric lattice structure by focusing on the role of magnetic frustration arising from the multi-subl…
Checkerboard bubble lattice formed by octuple-period quadruple- spin density waves
Satoru Hayami
We investigate multiple- instability on a square lattice at particular ordering wave vectors. We find that a superposition of quadruple- spin density waves, which are connect…
Uniform and Staggered electric axial moment in zigzag chain
Satoru Hayami
We theoretically investigate electronic orderings with the electric axial moment without breakings of both spatial inversion and time-reversal symmetries in the zigzag-chain system…
Chern insulating state with double- ordering wave vectors at the Brillouin zone boundary
Satoru Hayami
Magnetic multiple- states consisting of multiple spin density waves are a source of unconventional topological spin textures, such as skyrmion and hedgehog. We theoretically inv…
