Abstract

Structural properties at 30 K of Fe64Ni36 and Fe72Pt28 Invar alloys have been investigated through x-ray diffraction experiments up to 20 GPa. The Invar magnetovolumic characteristic property clearly affects the equation of state of both Fe-Ni and Fe-Pt samples between 2 and around 6 GPa. A fit function based on the 2- state model is used to analyze our p,V,T data and is shown to be suitable to interpret them.

Abstract

International audience; X-ray diffraction and ultrasonic measurements have been carried out simultaneously up to 7 GPa at ambient temperature on a polycrystalline sample of Fe 64 Ni 36 Invar alloy. The bulk modulus is found to increase linearly with pressure with an unusual low value (1.4) of dB/dP up to about 3.1(2) GPa followed by a regular slope (3.6) at higher pressure. The observation of these two distinct regimes is in qualitative agreement with previous results on the variation of the iron magnetic moment, and can be interpreted using the 2 γ-state model in terms of gradual population of low spin-small volume state at the expense of the high spin-large volume state under pressure.
