Spin textures with nontrivial topology, such as vortices and skyrmions, have attracted
attention as a source of unconventional magnetic, transport, and optical phenomena …

We theoretically investigate multiple-Q spin textures, which are composed of superpositions
of spin density waves with different wave numbers, for an effective spin model of …

We present a systematic study of higher-order exchange interactions beyond the pairwise
Heisenberg exchange in transition metal trilayers based on density functional theory …

We systematically investigate the structural, electronic, and magnetic properties of a new
pentagonal CoBiS monolayer using first-principles and Monte Carlo simulations. We find …

We propose a quartic chiral term mxmymz∇· m for the energy density of a cubic ferromagnet
with broken parity symmetry (point group T d). We demonstrate that this interaction causes a …

Thanks to the rapid development of the fabrication techniques in nanotechnology, the
building blocks of several nanodevices reached the atomic scale. Scientists and engineers …
