· Tm1 In1 Cu4

Tm₁In₁Cu₄ is an intermetallic compound combining thulium (a rare-earth element), indium, and copper in a fixed stoichiometric ratio. This is a research-phase material primarily studied for its potential electronic and thermoelectric properties rather than a commercial engineering material with established industrial use. The compound belongs to the family of rare-earth intermetallics, which are of interest in solid-state physics and materials research for understanding electronic structure, magnetic behavior, and potential applications in advanced electronic devices.
