Extended Data Figure 7: Electronic band structure of Os at moderate compressions along the high-symmetry lines in the hcp Brillouin zone.

a–d, Band structure of Os at 0 GPa (a, b) and at 134 GPa (c, d). Energies are given relative to the Fermi energy. In a and c, spin–orbit coupling has been included, whereas in b and d, the energies were obtained with the scalar-relativistic approximation. Experimental lattice parameters were used in the calculations (see Extended Data Fig. 4). Bands are shown in different colours for clarity.
