· JVASP-41470· Tm2CoIr

Tm2CoIr is an intermetallic compound combining thulium (rare earth), cobalt, and iridium in a stoichiometric ratio. This is a research-phase material studied for its potential in high-performance applications requiring dense, stiff materials with tailored magnetic and electronic properties. The combination of a rare earth element with transition metals (Co, Ir) positions it within the broader family of rare-earth intermetallics explored for advanced aerospace, electronics, and functional material applications where conventional alloys reach performance limits.
