New high-pressure phases of Fe(7)N(3) and Fe(7)C(3) stable at Earth's core conditions: evidences for carbon–nitrogen isomorphism in Fe-compounds
We carried out ab initio calculations on the crystal structure prediction and determination of P–T diagrams within the quasi-harmonic approximation for Fe(7)N(3) and Fe(7)C(3). Two new isostructural phases Fe(7)N(3)-C2/m and Fe(7)C(3)-C2/m which are dynamically and thermodynamically stable under the...
