Superconductivity at 8 K was reported in b-FeSe with a tetragonal PbO structure but not in d-FeSe with a hexagonal NiAs structure. The superconducting transition temperature was then increased up to 37 K (on-set) by high pressure on polycrystalline samples. We report a study of the characterization
