Effect of heavy-ion irradiation on London penetration depth in overdoped Ba(Fe1−xCox)2As2
Physical Review B
Irradiation with 1.4 GeV ^208Pb ions was used to induce artificial disorder in single crystals of iron-arsenide superconductor Ba(Fe_1-xCo_x)_2As_2 and to study its effect on the temperature-dependent London penetration depth and transport properties. Study was undertaken on overdoped single crystals with x=0.108 and x=0.127 characterized by notable modulation of the superconducting gap. Irradiation with doses 2.22×10^11d/cm^2 and 2.4×10^11d/cm^2, corresponding to the matching fields of B_ϕ = 6doi:10.1103/physrevb.88.054514 fatcat:odbz6lvb6vdxrgz6rc5aigrpsu
