  • When doubly-degenerate band crossings known as Kramers nodal lines intersect the Fermi level, they form exotic three-dimensional Fermi surfaces composed of massless Dirac fermions. Here, the authors present evidence that the 3R polytypes of TaS2 and NbS2 are Kramers nodal line metals with open octdong and spindle-torus Fermi surfaces, respectively.

  • In this work, the researchers realize the current-induced motion of Néel type chiral domain walls via spin-transfer-torque in the pristine van der Waals ferromagnet Fe3GeTe2 and via spin-orbit-torques in heterostructures with platinum or tungsten.

  • Current limitations of spintronics devices based on bulk topological materials stimulate the search for new materials and structures with interesting spin properties. Here the authors report a chiral spin texture around the Fermi level related to structural symmetry breaking in a TaSe2 layer grown on a Bi2Se3 surface.

  • Strong electron–electron interactions create a charge-density wave that modifies the topological state of the Weyl semimetal (TaSe4)2I. This implies the possibility of experimentally simulating axion electrodynamics in a solid-state material.

  • The two-dimensional layered crystal structure of niobium oxide polymorph T-Nb2O5 exhibits fast Li-ion diffusion that is promising for energy storage applications. Epitaxial growth of single-crystalline T-Nb2O5 thin films with ionic transport channels oriented perpendicular to the surface are now demonstrated.

  • Controlling the magnetization of a material is a major goal of spin-based information processing. One extensively studied method is to use spin-currents, generated from charge currents via the spin hall effect, however, the resulting spin polarization is typically limited to in-plane orientations. Here, Hazra et al demonstrate the presence of out-of-plane polarized spin-currents, which arise due to spin swapping at the Mn3Sn/permalloy interface.

  • Quasicrystals are perfectly ordered crystals lacking translational symmetry. Here the authors unravel the formation mechanism of two-dimensional dodecagonal quasicrystals that arise from systematic modifications of a hexagonal honeycomb structure.

  • Here, Saha et al. show that self-intercalation of e2Cr atoms in CrTe2 create an asymmetry in the number of atoms intercalated in the van der Waals gaps between the layers of CrTe2. This inversion symmetry breaking leads to non-collinear spin-textures and Néel-type magnetic skyrmions over a wide temperature range.
