a Reduction of the indirect and direct band gaps with pressure increase. The indirect band gap closes at around 20 GPa, terminating the insulating state and giving rise to BM state while the direct band gap manifests nonlinear curvature against pressure and survives beyond 40 GPa, retaining the BM state. b The magnetic moment of the Os ion indicating its gradual suppression along with applied pressure.
