ErCo2

ErCo2 is an intermetallic compound combining erbium (a rare-earth element) with cobalt in a 1:2 stoichiometric ratio. This material belongs to the family of rare-earth transition-metal intermetallics, which are typically studied for their magnetic, thermal, and mechanical properties at elevated temperatures. ErCo2 is primarily of research and specialized industrial interest rather than a commodity material, valued for applications requiring materials that combine rare-earth magnetic characteristics with cobalt's thermal stability and strength contributions.
