Overview

About HoSnAu

HoSnAu is a distinct intermetallic compound characterized by its semimetallic electronic nature. As a thermodynamically stable phase residing on the convex hull, it represents a robust configuration of holmium, tin, and gold atoms that maintains structural integrity under standard conditions. The material is notable for its structural diversity, having been identified in multiple distinct arrangements within crystallographic databases. This versatility makes it a subject of interest for researchers investigating the complex interplay between rare-earth magnetism and metallic bonding in ternary systems.
