Abstract

The newly discovered superconductor FeSe_1-x (x≈ 0.08, T _c^onset≈ 13.5 K at ambient pressure rising to 27 K at 1.48 GPa) exhibits a structural phase transition from tetragonal to orthorhombic below 70 K at ambient pressure - the crystal structure in the superconducting state shows remarkable similarities to that of the REFeAsO_1-xF _x (RE = rare earth) superconductors.
