Momentum-resolved superconducting gap in the bulk of Ba<sub>1−<i>x</i></sub>K<sub><i>x</i></sub>Fe<sub>2</sub>As<sub>2</sub>from combined ARPES and μSR measurements
Here we present a calculation of the temperature-dependent London penetration depth, λ(T), in Ba1-xKxFe2As2 (BKFA) on the basis of the electronic band structure (Zabolotnyy et al 2009 Nature 457 569, Zabolotnyy et al 2009 Physica C 469 448) and momentum-dependent superconducting gap (Evtushinsky et al 2009 Phys. Rev. B 79 …
