Abstract
We have performed nuclear magnetic resonance (NMR) measurements on an underdoped single-crystal Ba0. 77K0. 23Fe2As2 with Tc = 16. 5 K. Below TN = 46 K, an internal magnetic field splits the NMR peaks of H ∥ c and shifts those of H ∥ a to higher frequencies. The nuclear spin-lattice relaxation rate 1/T1 measured at the central peak with H ∥ a shows a distinct decrease below Tc(μ0H = 12 T) = 16 K. Our results clearly show that antiferromagnetic order and superconductivity coexist at a microscopical length scale.
