In this talk, I will outline our theoretical and experimental efforts to understand the root causes behind the experimental disconnect with theory in Heusler systems. 800+ ternary Heusler systems have been evaluated via density functional theory, and we will suggest a simple “4-2” rule for determining the absolute phase and relative Full/Inverse ordering stability of Heusler alloys and demonstrate high correlation to relative formation energy differences.
Please bring your own towel.
