This book offers a comprehensive survey of the latest research concerning high-entropy alloy (HEA) superconductors, an emerging topic which has attracted significant attention since their discovery in 2014. HEAs represent a novel class of materials introduced in 2004, renowned for their exceptional mechanical attributes, robust resistance to corrosion, and remarkable thermal stability, among other characteristics. Superconductivity has emerged as a particularly prominent subject in this domain. Recent important findings are robust superconductivity under extraordinarily high pressure or ion irradiation, possible unconventional superconductivity, enhancement of bulk superconductivity, and high critical current density.
In this book, HEA superconductors are classified into two primary categories: The first class encompasses alloy systems characterized by body-centered cubic and hexagonal close-packed structures; and the second class comprises intermetallic types. In each of these classes, the authors expound upon the exotic properties, applications, and materials design, aligning with the overarching themes of their work.
This book delivers a topical and timely discussion of superconductivity associated with the high-entropy state, the potential applications under consideration, and the intricacies of materials design. These recent discoveries are poised to captivate many researchers in materials science, particularly those engaged in high-entropy alloys and the realm of superconducting properties and technology.
