Phase diagram of Mn-doped Iron Oxo-Selenides
The cuprate oxide and the iron pnictide superconductors share many similarities but differ also in central characteristics. Despite the fact that the parent phases of the know Fe-superconductors are metal, the physics of these materials reveal more and more an interplay between itinerant and localized magnetism. We use an iron oxo-selenide compound with similar structural and magnetic properties as the known iron superconductors. By doping the parent compound on different positions we want to understand the developement of the magnetic and electric properties in the iron selenides under different conditions. In this experiment we want to investigate the temperature dependance of the crystallographic and magnetic structure of the La2O3Fe(2-x)Mn(x)Se2 series that show a very interesting magnetization curve with several transitions to finally map out a magnetic phase diagram for this system.
