Using Curie temperatures (Tc) of Heusler alloys calculated by the Korringa-Kohn-Rostoker Green function (KKR-GF) method and a subsequent Monte Carlo (MC) approach [1], we trained and evaluated several machine learning models to predict Tc based on atomic, magnetic, and structural properties. We studied multiple descriptor selection methods to determine the most meaningful physical quantities in the given phase space.We compared the performance of regression and classification models in order to predict the range of the Tc of given compounds without performing the MC calculations. Since the MC calculation takes about as many computational resources as the ab-initio calculation, it would be favorable to replace either step with a less computational intensive method as e.g. machine learning. We discuss the necessity to generate the magnetic ab-initio results in order to make a quantitative prediction of the Tc.This work can be seen as a small-scale case study in which lightweight machine learning algorithms can add value to existing ab-initio data and eventually replace costly computational steps in layered calculation workflows in the future.[1] R.
