Communicating skyrmions as the main mechanism underlying skyrmionium (meta)stability in quasi-two-dimensional chiral magnets
Kaito Nakamura, Andrey O. Leonov
We re-examine the internal structure of skyrmioniums stabilized in quasi-two-dimensional chiral magnets with easy-axis uniaxial anisotropy. Skyrmioniums are particle-like states of…
Field-driven metamorphoses of isolated skyrmions within the conical state of cubic helimagnets
Andrey O. Leonov, Catherine Pappas, Ivan I. Smalyukh
Topologically stable field configurations appear in many fields of physics, from elementary particles to condensed matter and cosmology. During the last decade, chiral liquid cryst…
Field and anisotropy driven transformations of spin spirals in cubic skyrmion hosts
Andrey O. Leonov, Catherine Pappas, Istvan Kézsmárki
We discuss distinctive features of spiral states in bulk chiral magnets such as MnSi and CuOSeO that stem from the effect of the cubic magneto-crystalline anisotropy. First…
Stability of in-plane and out-of-plane chiral skyrmions in epitaxial MnSi(111)/Si(111) thin films: surface twists versus easy-plane anisotropy
Andrey O. Leonov, Ivan M. Tambovtcev, Igor S. Lobanov +1
The revisited theoretical phase diagrams for thin films of cubic helimagnets with the easy-plane anisotropy are shown to have different topology as previously reported [Phys. Rev.…
Real-space observation of skyrmion clusters with mutually orthogonal skyrmion tubes
Hayley. R. O. Sohn, Sergei M. Vlasov, Valeriy M. Uzdin +2
We report the discovery and direct visualization of skyrmion clusters with mutually-orthogonal orientations of constituent isolated skyrmions in chiral liquid crystals and ferromag…
Skyrmion instabilities and distorted spiral states in a frustrated chiral magnet
Thomas T. J. Mutter, Andrey O. Leonov, Katsuya Inoue
Magnetic skyrmions are particle-like topological excitations that recently generated much interest as candidates for future spintronic devices based on skyrmion small size, enhance…
