【 摘 要 】

We report measurements of the London penetration depth [Delta lambda(T)] of the recently discovered iron-based superconductor (Li1- xFex) OHFeSe, in order to characterize the nature of the superconducting gap structure. At low temperatures, Delta lambda(T) displays nearly temperature-independent behavior, indicating a fully open superconducting gap. We also analyze the superfluid density rho(s)(T), which cannot be well accounted for by a single- gap isotropic s-wave model but is consistent with either a two-gap model, a model for the orbital selective s x tau(3) state, or anisotropic s-wave superconductivity.
