Fig. 2: Aggregation of compositions into phase fields.
a Distribution of phase fields of magnetic materials in MPDS1 with respect to the maximum associated Curie temperature TC. The materials’ classes “low-temperature” and “high-temperature” magnets are divided at TC = 300 K as 2726:2027 phase fields. b Distribution of phase fields of superconducting materials (joined datasets from SuperCon3 and MPDS) with respect to the maximum associated superconducting transition temperature Tc. The materials’ classes “low-temperature” and “high-temperature” superconductors are divided around Tc = 10 K as 3311:1515 phase fields. c Distribution of phase fields of materials with a reported value of energy gap in MPDS with respect to the maximum associated bandgap. The materials’ classes “small-gap” and “large-gap” are divided around E = 4.5 eV as 20910:19690 phase fields. d Distributions of materials with respect to the number of constituent elements are similar for all datasets: the majority of the reported compositions belong to ternary, quaternary and quinary phase fields. e Content of individual chemical elements among the explored materials in the databases; the total numbers of phase fields in the corresponding datasets are given in the legend. All datasets have similar trends with pronounced peaks for materials containing, e.g. carbon, oxygen and silicon. The inset illustrates an overlap in trends for elemental distribution in explored materials for superconducting and magnetic applications, where the peaks of the prevalent constituent elements are highlighted.
