Superfluid density and field-induced magnetism in Ba(Fe1−xCox)2As2 and Sr(Fe1−xCox)2As2 measured with muon spin relaxation
Abstract
We report muon spin rotation (μSR) measurements of single-crystal Ba(Fe1−xCox)2As2 and Sr(Fe1−xCox)2As2. From measurements of the magnetic field penetration depth λ we find that for optimally and overdoped samples, 1/λ(T→0)2 varies monotonically with the superconducting transition temperature TC. Within the superconducting state we observe a positive shift in the muon precession signal, likely indicating that the applied field induces an …
