Results obtained with both techniques on Fe-Pt samples can be well interpreted through the 2γ-state interpretation of the Invar effect. For the Fe64Ni36 alloy, the relative evolution of the iron magnetic moment at 300 K, measured through XMCD, shows the existence of a plateau between 4 and 10 GPa, also expected within this approach. In the low-pressure range, the evolution of magnetization indicates that the itinerant character of Fe-Ni alloys may affect the transition.
