Anion height dependence of<i>T</i>_cfor the Fe-based superconductor

Abstract

We have established a plot of the anion height dependence of Tc for the\ntypical Fe-based superconductors. The plot appeared a symmetric curve with a\npeak around 1.38 A. Both data at ambient pressure and under high pressure\nobeyed the unique curve. This plot will be one of the key strategies for both\nunderstanding the mechanism of Fe-based superconductivity and search for the\nnew Fe-based superconductors with higher Tc.\n
