Wykład zaproszony prof. Shiv J. Singh'a podczas International Symposium on Superconductivity (ISS2026) Japan

Prof. Shiv J. Singh from the Laboratory of Superconductors and Hydrogen Technologies (NL-6) has been invited to deliver a talk at the 39th International Symposium on Superconductivity (ISS2026), to be held from 1–3 December 2026 in Toyama, Japan.

Prof. Singh is among the invited speakers in the Wires and Bulk (WB) session. His invited presentation, entitled “Complete Electronic and Superconducting Phase Diagram of Fluorine-Doped PrFeAsO1-xFx,” will focus on a systematic investigation of the structural, electronic, magnetic, and superconducting properties of fluorine-doped PrFeAsO1-xFx over a broad range of fluorine concentrations. The study combines structural characterization, Raman spectroscopy, density functional theory calculations, electrical transport, magnetotransport, magnetization, and specific-heat measurements to establish the electronic and superconducting phase diagram of this iron-based superconductor. Superconductivity is observed over a broad fluorine-doping range, from x = 0.15 to 0.7, with a maximum transition temperature of ~52 K at x = 0.7. The work reports the first comprehensive electronic and superconducting phase diagram of a Pr-based iron oxypnictide superconductor.

The invitation reflects the international recognition of research conducted at the Institute of High Pressure Physics, Polish Academy of Sciences, in the field of iron-based superconductors and superconducting materials.
