We investigate how to engineer an antisymmetric spin-split band structure under spin density waves with finite ordering wave vectors in centrosymmetric systems without the relativistic spinorbit coupling. On the basis of a perturbative analysis for the spin-charge coupled model in centrosymmetric itinerant magnets, we show that nonzero chiral-type bilinear and biquadratic spin cross products in momentum space under the magnetic orderings are related to an antisymmetric spin polarization in the…

Spin susceptibility in superconductors without inversion symmetry

In materials without spatial inversion symmetry, the spin degeneracy of the conduction electrons can be lifted by an antisymmetric spin–orbit coupling. We discuss the influence of this spin–orbit

Emergent spin-valley-orbital physics by spontaneous parity breaking

The possibility of generating the spin-orbital entanglement by spontaneous electronic ordering caused by electron correlations is theoretically investigated, focusing on the centrosymmetric lattices with local asymmetry at the lattice sites, e.g. zigzag, honeycomb, and diamond structures.

Giant Rashba-type spin splitting in bulk BiTeI.

The finding of a huge spin-orbit interaction effect in a polar semiconductor composed of heavy elements, BiTeI, where the bulk carriers are ruled by large Rashba-likespin splitting is described, confirming that the spin splitting is indeed derived from bulk atomic configurations.

Spontaneous skyrmionic lattice from anisotropic symmetric exchange in a Ni-halide monolayer

The first-principles and Monte Carlo simulations reveal that the anisotropies of the short-range symmetric exchange, when combined with magnetic frustration, can lead to an emergent chiral interaction that is responsible for the predicted topological spin structures.

Nanometric skyrmion lattice from anisotropic exchange interactions in a centrosymmetric host

Skyrmion formation in centrosymmetric magnets without Dzyaloshinskii–Moriya interactions was originally predicted from unbiased numerical techniques. However, no attempt has yet been made, by

Multiply periodic states and isolated skyrmions in an anisotropic frustrated magnet

The phase diagram of an anisotropic frustrated magnet which contains five different multiply periodic states including the skyrmion crystal is studied to show that skyrMion materials with rich physical properties can be found among frustrated magnets.

Transformation between meron and skyrmion topological spin textures in a chiral magnet

Real-space observations of spin textures in a thin plate of the chiral-lattice magnet Co8Zn9Mn3, which exhibits in-plane magnetic anisotropy, demonstrate the rich variety of topological spin textures and their lattice forms and should stimulate further investigation of emergent electromagnetic properties.

Multiple-scattering approach for multi-spin chiral magnetic interactions: application to the one- and two-dimensional Rashba electron gas

Various multi-spin magnetic exchange interactions (MEI) of chiral nature have been recently unveiled. Owing to their potential impact on the realisation of twisted spin-textures, their future

Temperature-driven transition from skyrmion to bubble crystals in centrosymmetric itinerant magnets

Interplay between itinerant electrons and localized spins in itinerant magnets gives rise to a variety of noncoplanar multiple-Q spin textures, such as the skyrmion, hedgehog, meron, and vortex. We

Maximal Rashba-like spin splitting via kinetic-energy-coupled inversion-symmetry breaking

The findings therefore provide opportunities for creating spin-textured states and suggest routes to interfacial control of inversion-symmetry breaking in designer heterostructures of oxides and other material classes.
