Abstract
Resistivity measurements carried out on Fe3Pt invar alloys do not reveal a λ type anomaly near the Curie temperature Tc as usually observed on ferromagnetic materials. The Fe3Pt ordered alloy shows two very narrow peaks near Tc and a partially ordered alloy does not show any anomaly. As the Fe3Pt alloys are well known for their strong invar effect, we believe that such a behaviour results from critical electron‐phonon scattering arising from the strong lattice softening near Tc. Attempted explanation is given based on bulk modulus data.This publication has 11 references indexed in Scilit:
