· Ba2AsAu

Ba2AsAu is an intermetallic compound composed of barium, arsenic, and gold, belonging to the class of metallic intermetallics. This material is primarily of research interest rather than established in widespread industrial use, investigated for its potential electronic and structural properties in the context of complex metal phases and rare-earth-free magnetic or semiconducting applications.
