· JVASP-15645· HoCo2Si2

HoCo₂Si₂ is an intermetallic compound combining holmium, cobalt, and silicon, belonging to the rare-earth transition metal silicide family. This material is primarily investigated in research contexts for high-temperature structural applications and magnetic device applications, where its combination of metallic bonding and intermetallic ordering provides potential advantages in strength and thermal stability. The addition of holmium—a rare-earth element with notable magnetic properties—distinguishes this compound from conventional cobalt silicides, making it of particular interest for specialized aerospace, energy, and advanced manufacturing sectors seeking materials that maintain performance at elevated temperatures or in magnetically active environments.
