  • The consequences of electron-electron interactions are difficult to calculate reliably but this is needed to understand important physical properties such as ferromagnetism. Tusche et al. show that interaction effects in cobalt are nonlocal, presenting a challenge to future theoretical approaches.

  • It has been predicted that elemental Iron, with low dimensionality, will be a topological metal hosting Weyl nodes. Here, Chen et al. grow iron on tungsten, a heavy metal with a strong spin-orbit interaction, and using momentum microscopy, show the emergence of giant open Fermi arcs which can be shaped by varying the magnetization of the iron.

  • In semiconductors containing heavy elements, the Rashba spin-orbit interaction can couple the momentum and spin of electrons, yielding spintronic functionality. Here, the authors image band- and orbital-dependent spin-textures in the layered polar semiconductor BiTeI, demonstrating behaviour beyond the standard Rashba model.

  • 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.

  • Spintronic devices, where the spin of the electron becomes the main carrier of information, offer a promising avenue to develop quantum devices. The authors experimentally and theoretically investigate spin-polarization and spin-orbit mixing in a W(110) surface, and provide a mean to fine tune the quantum (de)coherence of materials by changing the spin polarization of a conduction electron in a spintronic device
