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 internal magnetic field. The size of the induced field decreases with increasing doping but is present for all Co concentrations studied. |
