A first-principles study of the structural, electronic and elastic properties of the FeO 2 -FeO 2 He system under high pressure

The origin of the wave velocity anomalies at the core-mantle boundary (CMB) has been controversial. The primordial helium reservoir in the deep lower mantle remains elusive even with geochemical evidence for its existence. Here, we calculated the density and wave velocity of the FeO -FeO He system u...
