In a paper published today, and using data from our ECHIDNA high-resolution powder diffractometer, in the prestigious journal Nature Materials, Hiroki Takahashi from Nihon University and co-authors from Japan, China and Australia, including our own Max Avdeev, revealed that barium iron sulphide (BaFe2S3) exhibits superconductivity under pressure (11 GPa) at a temperature below 14K.
For the first time, there is evidence of superconductivity on ladders of iron atoms, as opposed to planes. The other collaborators on the paper included researchers from the Tohoku University, University of Tokyo, National Institute for Materials Science, and Toyota Physical and Chemical Research Institute (Japan) and Jilin University (China).
