Abstract

High entropy alloys (HEAs) have recently emerged as a new class of materials. Solids made from multiple transition metal elements, typically five or more, in equimolar or near equimolar ratios, they are stabilized by entropic contributions to the free energy. 3d-element-based HEAs have been widely studied in materials science. In addition to their promising mechanical properties, some HEAs have been reported to display superconductivity; these materials are largely based on 4d and 5d metals. In this update, we focus on the variations of HEA superconductors presently known and the progress made in studies of their properties, especially highlighting fundamental issues related to their superconducting transition temperatures. Some of the key factors that influence their characteristics include crystal structure, atomic makeup, valence electron count, molar volume and mixing entropy - all of these factors appearing to be influential in spite of the fact that the materials are most like metallic glasses on simple periodic lattices. Many opportunities and challenges remain for expanding our knowledge of HEA superconductors, finding new types of HEA superconductors, and their potential for applications.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
