Query: Non-Magnetic Half-Metals   Half-metals are a class of materials that are metallic only for one spin
direction, and are essential for spintronics applications where one needs to
read, write, store and transfer spin-data. This spin sensitivity appears to
restrict them to be magnetic, and the known examples indeed are. The
fabrication of real spintronic devices from such materials is often hampered,
however, by stray magnetic fields, domain walls, short spin coherence times,
scattering on magnetic atoms or magnetically active interfaces, and other
characteristics that come along with the magnetism. The surfaces of topological
insulators, or Dirac or Weyl semimetals, could be an alternative, but
production of high-quality thin films without the presence of the bulk states
at the Fermi level remains very challenging. Here we introduce non-magnetic
half-metals and demonstrate that this state is realized in IrBiSe. Using
angle-resolved photoemission spectroscopy and band structure calculations we
find a record-high Dresselhaus spin-orbit splitting, fully spin-polarized
remnant Fermi surfaces and a chiral 3D spin-texture, all with no magnetism
present. Promising applications include using IrBiSe as a source of
spin-polarized electrons, and lightly doped IrBiSe is expected to generate
electric-field-controlled spin-polarized currents, free from back scattering,
and could host triplet superconductivity.
