EXTENDED ABSTRACT: Modem computational techniques, that use a combination of electronic structure calculations, adaptive genetic algorithms, and machine learning data analysis, have been recently predicting many new unknown structures that may exhibit desired physical properties. Yet, most of these theoretically discovered structures belong to the realm of virtual phase space, and the great challenge to experimentally observe them
still remains. Based on the example of the C36 Laves phase in Co-Fe-Ta system, we demonstrate a practical route to design and produce a material with desired properties. In particular, we demonstrated the possibility to synthesize rare-earth free permanent magnetic materials utilizing theoretical predictions based on large quantum-mechanical calculations. Such approach is general and can be applied in order to design experimentally route for a predicted material with desired properties.
Keywords: mateiral design, permanent magnets, magnetization curves,electronic structure, structure prediction
