About Permalloy
FeNi3 is a metallic alloy composed of iron and nickel that exists as a thermodynamically stable phase. Its electronic structure is characterized by metallic conductivity, reflecting its role as a robust and reliable material in various metallurgical applications. The compound is highly structurally documented, underscoring its prominence in materials science research and industrial engineering. Because it resides on the convex hull, it exhibits excellent long-term stability, making it a preferred choice for demanding environments where material integrity is paramount. Its unique magnetic characteristics stem from the specific arrangement of iron and nickel atoms, which are leveraged to create high-permeability materials essential for modern technology.
Key Properties
Cross-validated computational properties for Permalloy, aggregated across 5 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.
