Systematic ^{75}As NMR study of the dependence of low-lying excitations on F doping in the iron oxypnictide LaFeAs(O_{1-x}F_{x})

Yusuke Nakai, Shunsaku Kitagawa, Kenji Ishida +3

We report systematic $^{75}$ As NMR studies on LaFeAs(O $_{1 - x}$ F $_{x}$ ) ( $0 \leq x \leq 0.14$ ). At $x = 0.04$ near the phase boundary, from resistivity, spin-lattice relaxation rate $1/T_1…
