Chen Here, we experimentally study the origin of d -electron heavy fermion (HF) behavior in iron-based superconductors (FeSCs) A Fe 2 As 2 ( A = K , Rb, Cs). Nuclear magnetic resonance on As 75 reveals a universal coherent-incoherent crossover with a characteristic temperature T * . Below T * , a so-called “Knight shi… [Phys. Rev.
