Transverse-field muon spin rotation measurements were performed on the iron-based superconductor, KFe2As2, in order to investigate the superconducting gap mechanism. We found that the temperature dependence of the magnetic penetration depth λ shows multiple gap-like behavior and that λ depends on the field. These results suggest the existence of quasiparticle excitations outside the vortices.
