CrInNi2 is a metallic Heusler alloy that exists as a metastable phase of interest for fundamental materials research.
About CrInNi2
CrInNi2 belongs to the versatile family of Heusler alloys, which are known for their diverse magnetic and electronic properties. As a metallic compound, it exhibits characteristic conductivity associated with its crystalline structure, though it remains a subject of intense investigation due to its complex phase behavior.
This material is notable for its presence across multiple structural databases, reflecting significant interest from the computational materials science community. Its thermodynamic profile indicates that it exists in a metastable state, posing unique challenges and opportunities for synthesis and potential functional applications in advanced alloy design.
Key Properties
Cross-validated computational properties for CrInNi2, 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.

How It Compares
Within the heusler alloys class.
Unlike the highly stable and frequently studied NiSnTi or Ni1Sn1Ti1, CrInNi2 is classified as being above the thermodynamic hull, suggesting it is less stable under standard conditions. While many Heusler alloys are prized for their robust phase formation, this compound represents a more exotic, metastable member of the class that requires specific processing conditions to stabilize compared to its more conventional siblings like GaMnPd2.
