Marcenat We report on local magnetization, tunnel diode oscillators, and specific-heat measurements in a series of Ba(Ni x Fe 1− x ) 2 As 2 single crystals ( 0.26≤ x ≤0.74 ). We show that the London penetration depth λ ( T )= λ (0)+ Δ λ ( T ) scales as λ (0)∝1/ T c 0.85±0.2 , Δ λ ( T )∝ T 2.3±0.3 (for T 〈 T c /3 ), and ∂ Δ λ / ∂ T 2 ∝1/ T c 2.8±0.3 in ... [Phys. Rev.
