· ErNi4Au

ErNi₄Au is an intermetallic compound combining erbium, nickel, and gold, belonging to the rare-earth transition metal alloy family. This material is primarily of research interest for applications requiring the unique combination of rare-earth magnetism and noble metal stability, with potential use in advanced magnetic devices, specialized electronic components, and high-performance materials where corrosion resistance and thermal stability are critical. Its ternary composition makes it distinct from binary rare-earth nickel or gold-based systems, positioning it as an exploratory candidate in materials science rather than a commodity engineering material.
