· YCo

YCo is a rare-earth cobalt intermetallic compound belonging to the family of yttrium-cobalt systems, which are typically investigated for permanent magnet, high-temperature structural, or magnetic refrigeration applications. This material represents a research-phase compound rather than a commodity alloy; yttrium-cobalt phases are studied primarily for their magnetic properties and potential use in specialized high-performance contexts where conventional cobalt alloys are insufficient. The specific phase designation and thermal/mechanical stability make it relevant to materials scientists exploring advanced magnetic materials or high-temperature applications, though industrial adoption remains limited.
