| Abstract | oximate to 1.9 for x = 0.05 in the pristine state. Detailed analysis of lambda(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(Fe1-xNix)(4)As-4 at x = 0 is similar to a slightly overdoped Ba1-y K-y Fe2As2 at y approximate to 0.5, and at x = 0.05 to an underdoped composition at y approximate to 0.2. |
