The synthesis of new materials that can host magnetic skyrmions and their thorough experimental and theoretical characterization are essential for future technological applications. The $\ensuremath{\beta}$-Mn-type compound ${\mathrm{FePtMo}}_{3}\mathrm{N}$ is one such novel material that belongs to the chiral space group $P{4}_{1}32$, where the antisymmetric Dzyaloshinskii-Moriya interaction is allowed due to the absence of inversion symmetry. We report the results of small-angle neutron…

Dzyaloshinsky–Moriya interaction (DMI)-induced magnetic skyrmion materials

A magnetic skyrmion is a particle-like spin swirling object with a nontrivial topology that holds great promise for next-generation information carriers in high-performance spintronic devices. It was

Signature of anisotropic exchange interaction revealed by vector-field control of the helical order in a FeGe thin plate

The authors demonstrate the vector-field control of the magnetic screw axis in a chiral helimagnet and show that the spiral period varies the orientation of the screw axis with respect to the

Controlling Dzyaloshinskii-Moriya interactions in the skyrmion host candidates FePd1−xPtxMo3N

Ferromagnets crystallizing in structures described by chiral cubic space groups, including compounds with the B20 or $\beta$-Mn structures, are known to host long-period chiral spin textures such as
