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 …

The notion of non-trivial topological winding in condensed matter systems represents a
major area of present-day theoretical and experimental research. Magnetic materials offer a …

Magnetic nano-skyrmions develop quantized helicity excitations, and the quantum tunneling
between nano-skyrmions possessing distinct helicities is indicative of the quantum nature of …

Manipulating topological spin textures is a key for exploring unprecedented emergent
electromagnetic phenomena. Whereas switching control of magnetic skyrmions, eg, the …

A skyrmion crystal (SkX) expressed as a multiple number of spiral modulations manifests
itself not only in its peculiar magnetic texture but also in nontrivial transport properties …

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 magnetic skyrmion crystal is a periodic array of a swirling topological spin texture. Since
it is regarded as an interference pattern by multiple helical spin density waves, the texture …

EuAl 4 is a rare-earth intermetallic in which competing itinerant and/or indirect exchange
mechanisms give rise to a complex magnetic phase diagram, including a centrosymmetric …

Multiple-Q magnetic states, such as a skyrmion crystal, become a source of unusual
