Description
We report on a detailed study of the electronic phase diagram of FeSe1−x under pressure by means of muon-spin rotation and AC magnetization. Whereas at low pressures the system is solely superconducting at low-temperatures, one observes the occurrence of a static magnetic order at a pressure of ≃ 0.8GPa. For this pressure, bulk superconductivity coexists and competes on short length scales with the magnetic order below Tc. For pressures above 1GPa a remarkable enhancement of both the magnetic and the superconducting transition temperatures is observed. These unconventional properties establish FeSe1−x as one of the most intriguing superconducting systems investigated to date.
