Abstract

Face-centered-cubic iron (γ-Fe) coherently precipitated in a single crystal of Cu has been studied by neutron diffraction at high pressures up to 0.9 GPa and in the temperature range from about 5 to 110 K. It undergoes antiferromagnetic ordering at 67±2 K at ambient pressure. The ordering temperature T_N monotonically decreases with increasing pressure following a relation T_N(K)=67-12.8p - 11.1p² - 6.17p³, where p is in units of GPa. The change of T_N in γ-Fe is discussed in terms of the volume change caused by pressurization or by alloying.
