Bulk synthesis of iron-based superconductors

Exploratory synthesis efforts for iron-based superconductors (FeSCs) have been driven by hopes of improving superconducting critical temperatures (T(C)s), providing high-quality samples for in-depth studies of intrinsic properties, and exploring potential superconductivity in similar families of materials. This manuscript summarizes the synthesis routes that are used for producing FeSC and their undoped parents, in single crystal and polycrystalline forms. A few of the materials challenges are summarized. Published by Elsevier Ltd.
