The discovery of Fe " based superconductors has infused new vigor into the search for answers to the multifaceted question of high " transition temperature superconductivity. Four years on, Fe " compounds have grown into a wide class of materials spanning intermetallics and oxides, pnictides and chalcogenides. Chemical doping both induces and suppresses superconductivity, affecting the electronic structure in the former and acting as pair " breaking disorder in the latter case. Experimental and theoretical research indicates nontrivial competition of multiband electronic interactions and a diverse interplay of magnetism, including long"range, and superconductivity. In this talk I will outline our effort to understand the pairing mechanisms, effects of disorder and the emergence of a nematicity in various Fe " based superconductors.
