Title: In-plane magnetic penetration depth of superconducting ${CaKFe}_{4} {As}_{4}$

Abstract

Here, the temperature dependence of the in-plane magnetic penetration depth (λ_ab) in an extensively characterized sample of superconducting CaKFe₄As₄(T_c≃35K) was investigated using muon-spin rotation (μSR). A comparison of λ^–2_ab(T) measured by μSR with the one inferred from angle-resolved photoemission spectroscopy (ARPES) data confirms the presence of multiple gaps at the Fermi level. An agreement between μSR and ARPES requires the presence of additional bands, which are not resolved by ARPES experiments. These bands are characterized by small superconducting gaps with an average zero-temperature value of Δ₀=2.4(2)meV. Our data suggest that in CaKFe₄As₄ the s^± order parameter symmetry acquires a more sophisticated form by allowing a sign change not only between electron and hole pockets, but also within pockets of similar type.

Enhancement of the superconducting gap by nesting in ${CaKFe}_{4} {As}_{4}$ : A new high temperature superconductor

Journal Article Mou, Daixiang ; Kong, Tai ; Meier, William R. ; ... - Physical Review Letters

We use high resolution angle resolved photoemission spectroscopy and density functional theory with measured crystal structure parameters to study the electronic properties of CaKFe₄As₄. In contrast to the related CaFe₂As₂ compounds, CaKFe₄As₄ has a high T_c of 35 K at stochiometric composition. This presents a unique opportunity to study the properties of high temperature superconductivity in the iron arsenides in the absence of doping or substitution. The Fermi surface consists of several hole and electron pockets that have a range of diameters. We find that the values of the superconducting gap are nearly isotropic (within the explored portions of themore »« less

Anomalous phonon behavior in superconducting ${CaKFe}_{4} {As}_{4}$ : An optical study

Journal Article Yang, Run ; Dai, Yaomin ; Xu, Bing ; ... - Physical Review B

Here, the temperature dependence of ab-plane optical conductivity of CaKFe₄As₄ has been measured below and above its superconducting transition temperature T_c≃35.5 K. In the normal state, analysis with the two-Drude model reveals a T-linear scattering rate for the coherent response, which suggests strong spin-fluctuation scattering. Below the superconducting transition, the optical conductivity below 120 cm^–1 vanishes, indicating nodeless gap(s). The Mattis-Bardeen fitting in the superconducting state gives two gaps of Δ₁ ≃ 9 meV and Δ₂ ≃ 14 meV, in good agreement with recent angle-resolved photoemission spectroscopy (ARPES) results. In addition, around 255 cm^–1, we observe two different infrared-active Fe-Asmore »« less

In this paper, we report ⁷⁵As nuclear magnetic resonance (NMR) studies on a new iron-based superconductor, CaKFe₄As₄, with T_c = 35 K. ⁷⁵As NMR spectra show two distinct lines corresponding to the As(1) and As(2) sites close to the K and Ca layers, respectively, revealing that K and Ca layers are well ordered without site inversions. We found that nuclear quadrupole frequencies ν_Q of the As(1) and As(2) sites show an opposite temperature T dependence.

Nodeless multiband superconductivity in stoichiometric single-crystalline ${CaKFe}_{4} {As}_{4}$

Journal Article Cho, Kyuil ; Fente, A. ; Teknowijoyo, S. ; ... - Physical Review B

Measurements of the London penetration depth Δλ(T) and tunneling conductance in single crystals of the recently discovered stoichiometric iron-based superconductor CaKFe₄As₄ (CaK1144) show nodeless, two-effective-gap superconductivity with a larger gap of about 6–10 meV and a smaller gap of about 1–4 meV. Having a critical temperature T_c,onset ≈ 35.8 K, this material behaves similar to slightly overdoped (Ba_1–xK_x)Fe₂As₂ (e.g., x = 0.54,T_c ≈ 34 K), a known multigap s_± superconductor. Here, we conclude that the superconducting behavior of stoichiometric CaK1144 demonstrates that two-gap s± superconductivity is an essential property of high-temperature superconductivity in iron-based superconductors, independent of the degree ofmore » substitutional disorder.« less
