  • Materials with low magnetic damping are important for a range of applications but are typically insulating, which limits their use. Thanks to a unique feature of the band structure, similar levels of damping can now be achieved in a metallic alloy.

  • Terahertz frequencies offer the potential of much higher data transfer rates, but this requires devices able to generate and manipulate terahertz waves. One approach is to utilize the spin dynamics of a magnetic system. Here, Ilyakov et al. show how a multilayer magnetic and heavy-metal heterostructure can be used to achieve terahertz second harmonic generation and optical rectification.

  • Hitherto, only circularly polarized antiferromagnetic (AFM) spin-waves (SWs) were expected to convey spin-information. Here, the authors present persistent spin-transport over long distances in the easy-plane AFM phase of hematite, α-Fe2O3, via linearly polarized SW pairs with ultra-low damping.

  • Antiferromagnets are expected to be a key part of next generation electronic devices however their magnetic interactions prove difficult to access. Here, the authors demonstrate that the surface sensitive spin-Hall magnetoresistance, along with a simple analytical model, can successfully probe the internal anisotropies of the model antiferromagnet hematite (α-Fe2O3).

  • The discovery of spin-triplet Cooper pairs at superconductor/ferromagnet interfaces provides a route for combining superconducting and magnetic orders. Recent advances and challenges in the field of superconducting spintronics are now reviewed.
