Skyrmion, a concept originally proposed in particle physics half a century ago, can now find
the most fertile field for its applicability, that is, the magnetic skyrmion realized in …

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 …

The instability toward a magnetic skyrmion crystal in centrosymmetric trilayer magnets is
investigated based on a spin model with layer-dependent Dzayloshinskii-Moriya interaction …

We investigate the spin excitation spectra in chiral and polar magnets by the linear spin-
wave theory for an effective spin model with symmetric and antisymmetric long-range …

We theoretically report an instability toward a skyrmion crystal in centrosymmetric magnets
under hexagonal and trigonal single-ion anisotropy. The results are obtained for a minimal …

Topological defects and smooth excitations determine the properties of systems showing
collective order. We introduce a generic non-singular field theory that comprehensively …

We report investigations of the magnetic textures in periodic multilayers [Pt (1 nm)/(CoFeB
(0.8 nm)/Ru (1.4 nm)] 10 using polarised neutron reflectometry (PNR) and small-angle …

Physics of Weyl electrons has been attracting considerable interests and further accelerated
by recent discoveries of giant anomalous Hall effect (AHE) and topological Hall effect (THE) …

The discovery of two-dimensional (2D) materials with novel magnetism is a compelling
problem of condensed material physics and materials science but is still a challenge. Here …
