Abstract: We examine the effects of atomic vacancies on the (1) spin interaction, and (2) electronic character in the cubic B20 chiral magnet FeGe. For the former, Heisenberg exchange and Dzyaloshinskii-Moriya (DM) interactions are studied. The… read more here.

DOI: 10.1103/physrevb.100.121108
Abstract: We apply linked cluster expansion techniques to study the polarized high-field phase of a spin-half antiferromagnet on the Kagome lattice with Heisenberg and Dzyaloshinskii-Moriya interactions (DMI). We find that the Dirac points of the single-magnon… read more here.

DOI: 10.1103/physrevb.98.214414
Abstract: We use phenomenological symmetry arguments to demonstrate that while chiral magnetic (Dzyaloshinskii-Moriya) interactions are conventionally restricted by symmetry to appear in a limited set of noncentrosymmetric materials, they may arise in a material with any… read more here.

DOI: 10.3390/nano12071159
Abstract: A magnonic metamaterial in the presence of spatially modulated Dzyaloshinskii–Moriya interaction is theoretically proposed and demonstrated by micromagnetic simulations. By analogy to the fields of photonics, we first establish magnonic Snell’s law for spin waves… read more here.
