Iron based superconductors have been attracting considerable attention since their discoveryin 2008. In particular, simple binary iron chalcogenides have recently emerged to the frontier of research due to traces of superconducting critical temperatures (Tc’s) similar to copper oxide high-Tc superconductors. In this talk I will discuss characteristics of FeX and KxFe2-yX2 (X=Se,S). I will mention in a nutshell pair breaking mechanism, magnetic states and critical currents but I with focus on the normal states in high magnetic fields as T → 0 connected with the electronic and crystallographic phase separation. The presentation will also include brief discussion on magnetic states in semiconducting crystal structures with FeX building blocks.
