Robust ${s}_{\pm}$ pairing in $\mathrm{CaK}{\left({\mathrm{Fe}}_{1\u2013x}{\mathrm{Ni}}_{x}\right)}_{4}{\mathrm{As}}_{4}$ ( $x=0$ and 0.05) from the response to electron irradiation
Abstract
Here, controlled pointlike disorder introduced by 2.5MeV electron irradiation was used to probe the superconducting state of single crystals of CaK(Fe _{1–x}Ni _{x}) _{4}As _{4} superconductor at x = 0 and 0.05 doping levels. Both compositions show an increase of the residual resistivity and a decrease of the superconducting transition temperature, T _{c}, at the rate of dT _{c}/dρ(T _{c}) ≈ 0.19 K/(μΩcm) for x = 0 and 0.38 K/(μΩcm) for x = 0.05, respectively. In the Nidoped compound (x = 0.05), the coexisting spinvortex crystal (SVC) magnetic phase is suppressed at the rate of dT _{N}/dρ(T _{N}) ≈ 0.16 K/(μΩcm). The lowtemperature variation of London penetration depth is well approximated by the powerlaw function, Δλ(T) = AT ^{n}, with n ≈ 2.5 for x = 0 and n ≈ 1.9 for x = 0.05 in the pristine state. Detailed analysis of λ(T) and T _{c} evolution with disorder is consistent with two effective nodeless energy gaps in the density of states due to robust s± pairing. Overall the behavior of CaK(Fe _{1–x}Ni _{x}) _{4}As _{4} at x = 0 is similar to a slightly overdoped Ba _{1–y}K _{y}Fe _{2}As _{2} at y ≈ 0.5, and at x = 0.05more »
