The magnetic properties of the Invar alloy Fe₆₄Ni₃₆ have been investigated by x-ray emission spectroscopy as a function of pressure up to 20 GPa. With increasing pressure, the amplitude of the Fe local moment, deduced from the Fe Kβ line satellite intensity, is reduced at two characteristic step values. This pressure dependence is interpreted in terms of transitions from a high-spin state to a low-spin state at ≈5 GPa followed by a transition to a nonmagnetic state above 15 GPa. This behavior provides a microscopic picture of the Fe magnetism in agreement with the 2γ-state model.
