摘要: Abstract The magnetization and high-field susceptability of a series Fe 3 Pt alloys have been investigated as function composition degree atomic ordering. results indicate that these cannot be described in terms the model very weak itinerant ferromagnetism. Instead, data are fitted by which includes magnetoelastic term, leading turn to discussion magnetovolume relations Invar problem. is large, other Invars, dependent A minimum observed at 30 at% both ordered disordered phases. From existence it suggested FePt ferrimagnetic interactions may induced Pt-richer distortion cubic lattice. In general, constitute unique case among all characterized anomalies, used typify behaviour.
