Abstract
Wire heating in diamond‐anvil cells has been used to measure the pressure, temperature, resistance, and x‐ray diffraction patterns of γ‐Fe at pressures to 42 GPa and temperatures to 2340 K. The results can be described by a bulk modulus, K=127±8 GPa+2.2 (P/GPa). Extrapolation of these results to conditions of the earth’s core yields a density in good agreement with shock compression and of about 15% higher than estimates of the preliminary reference earth model.This publication has 7 references indexed in Scilit:
