· HoAu3

HoAu3 is an intermetallic compound combining holmium (a rare-earth element) with gold in a 1:3 stoichiometric ratio. This material belongs to the family of rare-earth gold intermetallics, which are primarily studied for their unique electronic and magnetic properties rather than mainstream structural applications. HoAu3 is largely confined to academic research and materials science investigations, where it serves as a model system for understanding rare-earth metallurgical behavior and potential applications in specialty electronics, magnetic devices, or high-performance alloy development.
