· JVASP-149208· FeNi2

FeNi2 is an iron-nickel intermetallic compound characterized by a 1:2 atomic ratio of iron to nickel, forming an ordered crystalline phase rather than a simple solid solution. This material is primarily investigated in research contexts for magnetic applications and as a potential constituent in advanced alloys, particularly in systems requiring controlled magnetic properties or high-temperature stability. Its ordered structure distinguishes it from conventional Fe-Ni solid solutions used in transformer cores and precision alloys, making it relevant for engineers developing specialized magnetic devices, electromagnetic shielding systems, or high-performance composite matrices where phase stability and magnetic behavior are critical design factors.
