Title: Effect of Electron Irradiation on Superconductivity in Single Crystals of Ba ( Fe 1 x Ru x ) 2 As 2 ( x = 0.24 )

Abstract

A single crystal of isovalently substituted Ba(Fe 1-xRu x) 2As 2 (x=0.24) is sequentially irradiated with 2.5 MeV electrons up to a maximum dose of 2.1×10 19 e -/cm 2. The electrical resistivity is measured in situ at T=22 K during the irradiation and ex situ as a function of temperature between subsequent irradiation runs. Upon irradiation, the superconducting transition temperature T c decreases and the residual resistivity ρ0 increases. We find that electron irradiation leads to the fastest suppression of T c compared to other types of artificially introduced disorder, probably due to the strong short-range potential of the pointlike irradiation defects. As a result, a more detailed analysis within a multiband scenario with variable scattering potential strength shows that the observed T c versus ρ 0 is fully compatible with s ± pairing, in contrast to earlier claims that this model leads to a too rapid suppression of T c with scattering.
