 Abstract: Due to the simple layered structure, isostructural FeSe and FeSe0.5Te0.5 are clue compounds for understanding the principal mechanisms of superconductivity in the family of Fe-based superconductors. High-pressure magnetic, structural and Mossbauer studies have been performed on single-crystalline samples of superconducting FeSe0.5Te0.5 with T-c=13.5K. Susceptibility data have revealed a strong increase of T-c up to 19.5K for pressures up to 1.3GPa, followed by a plateau in the T-c(p) dependence up to 5.0GPa. Further pressure increase leads to a disappearance of the superconducting state around 7.0GPa. X-ray diffraction and Mossbauer studies explain this fact by a tetragonal-to-hexagonal structural phase transition. Mossbauer parameters of the non-superconducting high-pressure phase indicate less covalency of FeSe bonds. Based on structural and susceptibility data, we conclude about a common character of T-c(p) diagrams for both FeSe and FeSe0.5Te0.5 superconductors. (C) 2016 WILEY-VCH Verlag GmbH & Co.
