Ba4YCu
metal· JVASP-64712· Ba4YCu
Ba4YCu is a barium-yttrium-copper intermetallic compound belonging to the family of rare-earth copper systems, primarily of research and developmental interest rather than established commercial production. This material is investigated for potential applications in superconductivity research and advanced functional ceramics, where the combination of barium, yttrium, and copper offers possibilities for studying electron transport and magnetic properties at cryogenic temperatures. While not yet widely deployed in mainstream engineering, compounds in this chemical family are of interest to materials researchers exploring next-generation superconductors and high-temperature electronic devices.
