NMR relaxation rate and lineshape. Temperature dependence of 1/T 1 relaxation rate measured at 7 T at the left peak of the 75As NMR lineshape (arrow in the inset). A similar 1/T 1 behavior is found also for the right peak. The steep decrease of 1/T 1 below T c is compatible with a fully gapped superconductor. Lines indicate different power-law dependences, at different temperature regimes (see text for details)
