Gruneisen's gamma function for liquid iron at the E a r t h 's outer core conditions

Abstract

SUMMARY. - WE derive the Gruneisen's gamma as a function of temperature and pressure for liquid iron at the temperature and pressures of the Earth's outer core taking into account the anharmonic and electronic contributions in a self-consistent way. We obtain numerical values definetely different from those generally quoted in the geophysical literature, but in agreement with recent experimental determinations.
