Abstract

This review presents a summary of our NMR experiments on LaFeAs(O1-xFx) and BaFe2(As1-xPx)2. The authors introduce the key NMR experimental results which reveal their physical properties in the normal and superconducting states. From the comparison of the NMR results between the two systems, we point out that the superconducting gap structure and the relationship between superconductivity and magnetic fluctuations probed with NMR are quite different between the two systems.
