Comparison of magnetic properties of Fe-Pt and Fe-Pd invar alloys with those of Fe-Ni invar alloys

Abstract Temperature dependence of the high-field susceptibility above 300 K for Fe-Pd and Fe-Pt Invar alloys has a strong resemblance to that of Fe-Ni Invar alloys. There exists also a large T 2 term in temperature decrease in magnetization for Fe-Pd and ordered Fe-Pt Invar alloys, similarly for Fe-Ni Invar alloys.
