  • Magnetically intercalated transition metal dichalcogenides provide a platform to study the interplay of magnetism, electronic band structures, and correlations. Here the authors demonstrate a nearly magnetization-free anomalous Hall effect, collinear antiferromagnetism and non-Fermi liquid behavior in V1/3NbS2.

  • The anomalous Nernst effect is usually associated with ferromagnets — enabling a temperature gradient to generate a transverse electric field — but the Berry curvature associated with Weyl points can drive this phenomenon in chiral antiferromagnets.

  • The rare-earth superconductor PrTr2Al20 (Tr = Ti, V) possesses quadrupolar and octupolar but no magnetic dipolar moments. Here, the authors suggest an intimate link between the quadrupolar order parameter and the superconducting pairing in this material.

  • In a Mn3Sn/W epitaxial bilayer, spin–orbit torque induces the coherent rotation of spins, which can couple to microwave currents. Unlike in ferromagnets, the resulting conversion of AC current to DC voltage remains robust at higher frequencies, which may facilitate the development of high-speed electronic devices.

  • The authors report observation of tunnelling magnetoresistance in an all-antiferromagnetic tunnel junction consisting of Mn3Sn/MgO/Mn3Sn, laying the foundation for the development of ultrafast and efficient spintronic devices using antiferromagnets.

  • Aluminium- and gallium-doped iron compounds show a large anomalous Nernst effect owing to a topological electronic structure, and their films are potentially suitable for designing low-cost, flexible microelectronic thermoelectric generators.

  • Antiferromagnetic Weyl semimetals based on Mn3X (X = Ge, Sn, Ga) kagome compounds exhibit significant electromagnetic responses even in the absence of large magnetization, but optimizing these effects across a wide temperature range is crucial for device applications. Here, the authors demonstrate that Mn3Sn1−xGax sputtered films offer tunable antiferromagnetic transition temperatures and enhanced anomalous Hall effect, paving the way for optimized antiferromagnetic materials in technological applications.

  • The large anomalous Hall (AHE) and anomalous Nernst effects (ANE) in antiferromagnets Mn3Sn/Mn3Ge are considered fingerprints of Weyl nodes residing near the Fermi energy. Here, the authors review the results from previous studies combining with new transport measurements on Mn3Sn/Mn3Ge single crystals, suggesting the essential role of magnetic Weyl fermions in explaining the AHE and ANE.
