FeO (Mg x = 0)

third-order Birch-Murnaghan · Original · 2017

Why this differs from similar rows?

Table I, low-spin (LS) phase value for Mg x = 0 (K0,T=210 GPa); sibling row is the high-spin (HS) phase of the same composition, K' fixed to 4.1 for both.

Evidence from the paper

TABLE I row Mg_x=0: K_{0,T}^{LS}=210 GPa; 'for the LS state our estimate of K_{0,T} is about 210 GPa'; 'K' ≡ dK/dP is fixed to 4.1 for all Mg compositions'; fit to third-order Birch-Murnaghan EOS separately for HS and LS volume regions at T = 1160 K.
