Spin-Lattice Coupling and Superconductivity in Fe Pnictides

Figure 3

Electron energy as a function of the Fe-As layer separation is calculated by LDA for , with spin polarization; the elastic constant is reduced by 29% compared to the state without spin polarization, accounting for the phonon softening by 15% due to spin polarization.
