Fig. 4

Compression curves of fcc-Ir along different isotherms. Temperatures are color-coded as in the legend. The solid lines are the isothermal compression curves calculated according to the thermal equation of state established in the present study. Empty triangles are from experimental thermal expansion point of Rh at ambient P. Dashed lines are from previous DFT simulations20.
