Ga1Mn1Ti2
Ga1Mn1Ti2 is a metastable semimetallic intermetallic compound composed of gallium, manganese, and titanium.
About Ga1Mn1Ti2
Ga1Mn1Ti2 is a complex intermetallic compound composed of gallium, manganese, and titanium. It exhibits a near-zero-gap electronic character, placing it in the category of semimetallic materials that often bridge the gap between conductive metals and semiconducting solids.
Due to its position above the thermodynamic hull, this compound is considered metastable, suggesting that its synthesis requires specific kinetic control. Its structural diversity is highlighted by numerous reported configurations, making it a subject of interest for those studying the phase stability of transition metal alloys.
Key Properties
