Yusenko, Kirill; Sottmann, Jonas; Emerich, Hermann; Crichton, WA; Malavasi, Lorenzo; Margadonna, Serena (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)Intercalation of Ba in β-FeSe by ammonothermal synthesis results in the formation of different superconducting phases with interlayer distance ranging between 8.4 and 13.1 Å. The values of Tc are primarily dependent on Ba ...
