Production method for a composite material comprising a FeSe supercondicting layer
Iron-based superconductors are superconducting materials characterized by high critical magnetic fields. By combining an electrochemical process with appropriate thermal treatments, it is possible to deposit thick (micrometer-scale) and compact layers on metallic substrates.

Problem to solve
Current deposition methods for iron-based superconducting materials rely on physical technologies such as thermal evaporation or laser ablation. The methodology developed by combining electrochemical deposition with appropriate heat treatments makes it possible to obtain a compact, thick superconducting layer without line-of-sight limitations, which is useful for niche applications that require deposition on curved or complex surfaces
Description
The proposed solution involves the electrochemical deposition of the superconductor precursor, followed by appropriate thermal treatments in reducing atmospheres in order to promote sintering and the onset of superconductivity.
