· JVASP-9074· ErNi3

ErNi3 is an intermetallic compound consisting of erbium and nickel, representing a rare-earth transition metal system with potential applications in specialized high-performance environments. This material belongs to the family of rare-earth intermetallics, which are primarily investigated for their unique magnetic, thermal, and structural properties at elevated temperatures. ErNi3 remains largely a research-stage compound; its adoption in industry is limited, but the material family shows promise for applications requiring thermal stability, magnetic control, or extreme-environment resilience where conventional alloys reach their limits.
