High-pressure structural study of Fe64Ni36 and Fe72Pt28 Invar alloys at low-temperature

Résumé

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.
