· Co2 Sn4 Er2

Co₂Sn₄Er₂ is an intermetallic compound combining cobalt, tin, and erbium—a research-phase material that belongs to the family of rare-earth transition metal stannides. This compound is primarily of academic and exploratory interest rather than established commercial use, studied for potential applications in magnetic, electronic, or thermoelectric systems where the combination of 3d (Co) and 4f (Er) electrons may produce useful coupling effects.
