Low resistivity contact to iron-pnictide superconductors

摘要

Method of making a low resistivity electrical connection between an electrical conductor and an iron pnictide superconductor involves connecting the electrical conductor and superconductor using a tin or tin-based material therebetween, such as using a tin or tin-based solder. The superconductor can be based on doped AFe₂As₂, where A can be Ca, Sr, Ba, Eu or combinations thereof for purposes of illustration only.
