Unconventional iron-magnesium compounds at terapascal pressures
Yimei Fang, Yang Sun, Renhai Wang +5
Being a lithophile element at ambient pressure, magnesium is long believed to be immiscible with iron. A recent study by Gao et al. [1] showed that pressure turns magnesium into a…

Prediction of crystal structures and motifs in the Fe-Mg-O system at Earth's core pressures
Renhai Wang, Yang Sun, Renata M. Wentzcovitch +6
Fe, Mg, and O are among the most abundant elements in terrestrial planets. While the behavior of the Fe-O, Mg-O, and Fe-Mg binary systems under pressure have been investigated, the…

Theoretical prediction of a highly responsive material: Spin fluctuations and superconductivity in FeNiB2 system
Renhai Wang, Yang Sun, Vladimir Antropov +3
By analyzing Fe-Ni-B compositional diagram we predict an energetically and dynamically stable FeNiB2 compound. This system belongs to the class of highly responsive state of materi…
