Phys. Rev. Lett. 104, 087004 (2010) [4 pages]Evolution of Two-Gap Behavior of the Superconductor FeSe1-xReceived 2 December 2009; published 25 February 2010 The superfluid density, ρs, of the iron chalcogenide superconductor, FeSe1-x, was studied as a function of pressure by means of muon-spin rotation. The analysis of ρs(T) within the two-gap scheme reveals that the effect on both, the transition temperature Tc and ρs(0), is entirely determined by the band(s) where the large superconducting gap develops, while the band(s) with the small gap become practically unaffected. © 2010 The American Physical Society URL:
