摘要
The magnetic properties of the Invar alloy Fe72Pt28 have been investigated by X-ray emission spectroscopy as a function of temperature up to 900 K and pressure up to 25 GPa, With increasing temperature and pressure, the amplitude of the Fe local moment, deduced from the Fe Kbeta line satellite intensity, is reduced. Both the temperature and pressure dependence are interpreted in terms of transitions from a high-spin state to a low-spin state. This behavior provides a microscopic picture of the Fe magnetism in Invar alloys in agreement with the 2gamma state model.
