· JVASP-15671· ErNi2B2C

ErNi2B2C is a ternary intermetallic compound combining erbium, nickel, boron, and carbon, belonging to the family of rare-earth transition-metal borocarbides. This material is primarily of research and development interest rather than widely commercialized, studied for its potential as a superconductor and high-performance structural material at cryogenic temperatures. The borocarbide family has attracted attention in materials science for combinations of superconductivity, hardness, and thermal stability, making ErNi2B2C relevant to exploratory applications in advanced electronics and extreme-environment engineering where conventional materials reach their limits.
