Sulfur annealing effect for superconductivity in iron chalcogenide compounds
arXiv:1308.5642 · doi:10.1063/1.4864417
Abstract
We discovered a novel annealing method for Fe-chalcogenide superconductors. It was found that sulfur annealing deintercalated excess Fe via formation of FeS2. Due to its specifics, sulfur annealing is applicable when preparing Fe-chalcogenide-based wires or cables.
