Title: Nodal to nodeless superconducting energy-gap structure change concomitant with Fermi-surface reconstruction in the heavy-fermion compound ${CeCoIn}_{5}$

Abstract

The London penetration depth, λ(T), was measured in single crystals of Ce_1-xR_xCoIn₅, R=La, Nd and Yb down to T_min ≈ 50 mK (T_c/T_min ~50) using a tunnel-diode resonator. In the cleanest samples Δλ(T) is best described by the power law, Δλ(T) ∝ Tⁿ, with n ~ 1, consistent with line nodes. Substitutions of Ce with La, Nd and Yb lead to similar monotonic suppressions of T_c, however the effects on Δλ(T) differ. While La and Nd dopings lead to increase of the exponent n and saturation at n ~ 2, as expected for a dirty nodal superconductor, Yb doping leads to n > 3, suggesting a change from nodal to nodeless superconductivity. As a result, this superconducting gap structure change happen in the same doping range where changes of the Fermi surface topology were reported, implying that the nodal structure and Fermi surface topology are closely linked.

Multiband superconductivity in the correlated electron filled skutterudite system ${Pr}_{1 - x} {Ce}_{x} {Pt}_{4} {Ge}_{12}$

Journal Article Singh, Y. P. ; Adhikari, R. B. ; Zhang, S. ; ... - Physical Review B

Studies of superconductivity in multiband correlated electronic systems have become one of the central topics in condensed-matter and materials physics. In this paper, we present the results of thermodynamic measurements on the superconducting filled skutterudite system Pr_1-xCe_xPt₄Ge₁₂ ( 0 ≤ x ≤ 0.2 ) to investigate how substitution of Ce at Pr sites affects superconductivity. We find that an increase in Ce concentration leads to a suppression of the superconducting transition temperature from T c ~ 7.9 K for x = 0 to T c ~ 0.6 K for x = 0.14 .

Electronic structure and $f$ -orbital occupancy in Yb-substituted CeCoIn $_{5}$

Journal Article Booth, C. H. ; Durakiewicz, T. ; Capan, C. ; ... - Physical Review. B, Condensed Matter and Materials Physics

The local structure and 4f orbital occupancy have been investigated in Ce_1-xYb_xCoIn₅ via Yb L_III-edge extended x-ray absorption fine structure (EXAFS), Ce and Yb L_III-edge x-ray absorption near-edge structure (XANES), and angle-resolved photoemission spectroscopy (ARPES) measurements. Yb(III) (4f¹³) is the hole analog of Ce(III) (4f¹). Yb is found to be strongly intermediate-valent in Ce_1-xYb_xCoIn₅ throughout the entire doping range, including pure YbCoIn5, with an f-hole occupancy for Yb of n_f≃0.3 (i.e., Yb^2.3+), independent of Yb concentration and independent of temperature down to T=20 K. In contrast, the f-electron orbital occupancy for Ce remains close to 1 for all Yb concentrations,more »« less

Robust $s_{\pm}$ pairing in $CaK {({Fe}_{1 - x} {Ni}_{x})}_{4} {As}_{4}$ ( $x = 0$ and 0.05) from the response to electron irradiation

Journal Article Teknowijoyo, S. ; Cho, K. ; Konczykowski, M. ; ... - Physical Review B

Here, controlled pointlike disorder introduced by 2.5-MeV electron irradiation was used to probe the superconducting state of single crystals of CaK(Fe_1–xNi_x)₄As₄ superconductor at x = 0 and 0.05 doping levels. Both compositions show an increase of the residual resistivity and a decrease of the superconducting transition temperature, T_c, at the rate of dT_c/dρ(T_c) ≈ 0.19 K/(μΩcm) for x = 0 and 0.38 K/(μΩcm) for x = 0.05, respectively. In the Ni-doped compound (x = 0.05), the coexisting spin-vortex crystal (SVC) magnetic phase is suppressed at the rate of dT_N/dρ(T_N) ≈ 0.16 K/(μΩcm).

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

Fermi surface reconstruction and dimensional topology change in Nd-doped ${CeCoIn}_{5}$

Journal Article Klotz, J. ; Götze, K. ; Sheikin, I. ; ... - Physical Review B

In this study, we performed low-temperature de Haas–van Alphen effect measurements on a Ce_1-xNd_xCoIn₅ series, for x = 0.02 , 0.05, 0.1, and 1, down to T = 40 mK using torque magnetometry in magnetic fields up to 35 T. Our results indicate that a Fermi surface (FS) reconstruction occurs from a quasi-two-dimensional topology for Nd-2% to a rather three-dimensional one for Nd-5% , thus reducing the possibility of perfect FS nesting. The FS evolves further with increasing Nd content with no observed divergence of the effective mass between Nd-2% and 10%, consistent with the crossing of a spin densitymore »« less
