Synthesis, structural and physical properties of δ′-FeSe 1-x

We report on synthesis, structural characterization, resistivity, magnetic and thermal expansion measurements on the as yet unexplored δ′-phase of FeSe 1-x, here synthesized under ambient-(AP) and high-pressure (HP) conditions. We show that in contrast to β-FeSe 1-x, monophasic superconducting δ′-Fe...
