Figure 2: Constrained LDA energies.
From: Proximity of iron pnictide superconductors to a quantum tricritical point
Energy per Fe for the MS (a, b), the OM phase (c, d) and the SCO phase (e) as a function of the Fe magnetic moment for different doping concentration x. The points are the results of LDA calculations whereas the continuous lines are fits using equation (1). (f) Energy per Fe for the MS phase for different values of the z coordinate of the As in the unit cell.
