Three-dimensional nodal superconducting gap in single crystals Ba(Fe $_{1 - x}$ Ni $_{x}$ ) $_{2}$ As $_{2}$

C. Martin, H. Kim, R. T. Gordon +6

The London penetration depth, $λ$ , is directly related to the density, $n_{s}$ , of the Cooper pairs ( $λ^{2} \propto 1/ n_{s}$ ) and its variation with temperature provides valuable in…

Superfluid density and specific heat within self-consistent scheme for two-band superconductor

V. G. Kogan, C. Martin, R. Prozorov

The two gaps in a two-band clean s-wave superconductor are evaluated self-consistently within the quasiclassical Eilenberger weak-coupling formalism with two in-band and one inter-…

Non-exponential London penetration depth in Ba $_{1 -}$ K $_{x}$ Fe $_{2}$ As $_{2}$ single crystals

C. Martin, R. T. Gordon, M. A. Tanatar +10

We have studied the in- and out-of-plane magnetic penetration depths in the hole- doped iron based superconductor Ba $_{1 - x}$ K $_{x}$ Fe $_{2}$ As $_{2}$ ( $T_{c} \approx$ 30K). The study…
