· DyAu2

DyAu₂ is an intermetallic compound combining dysprosium (a rare earth element) with gold in a 1:2 stoichiometric ratio. This material belongs to the rare earth–noble metal intermetallic family and is primarily of research interest rather than established industrial use, with potential applications in high-temperature materials, magnetic devices, and specialized electronic components where rare earth–gold interactions offer unique properties.
