Title: 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

Abstract

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). The low-temperature variation of London penetration depth is well approximated by the power-law function, Δλ(T) = ATⁿ, with n ≈ 2.5 for x = 0 and n ≈ 1.9 for x = 0.05 in the pristine state. Detailed analysis of λ(T) and T_c evolution with disorder is consistent with two effective nodeless energy gaps in the density of states due to robust s± pairing. Overall the behavior of CaK(Fe_1–xNi_x)₄As₄ at x = 0 is similar to a slightly overdoped Ba_1–yK_yFe₂As₂ at y ≈ 0.5, and at x = 0.05 to an underdoped composition at y ≈ 0.2.

Effect of Ni doping on vortex pinning in $CaK {(F e_{1 - x} N i_{x})}_{4} A s_{4}$ single crystals

Journal Article Haberkorn, N. ; Xu, M. ; Meier, W. R. ; ... - Physical Review B

We study the correlation between chemical composition and vortex dynamics in Ni-doped CaK(Fe_1–xNi_x)₄As₄ (x = 0, 0.015, 0.025, 0.03, and 0.05) single crystals by performing measurements of the critical current densities J_c and the flux creep rates S. The magnetic relaxation of all the crystals is well described by the collective creep theory. The samples display a glassy exponent μ within the predictions for vortex bundles in a weak pinning scenario and relatively small characteristic pinning energy (U₀ < 100K). The undoped crystals display modest J_c values at low temperatures and high magnetic fields applied along the c axis. J_c(T)more »« less

Hedgehog Spin-Vortex Crystal Antiferromagnetic Quantum Criticality in $CaK ({Fe}_{1 - x} {Ni}_{x})_{4} {As}_{4}$ Revealed by NMR

Journal Article Ding, Q. -P. ; Meier, W. R. ; Cui, J. ; ... - Physical Review Letters

Two ordering states, antiferromagnetism and nematicity, have been observed in most iron-based superconductors (SCs). In contrast to those SCs, the newly discovered SC CaK(Fe_1-xNi_x)₄As₄ exhibits an antiferromagnetic (AFM) state, called hedgehog spin-vortex crystal structure, without nematic order, providing the opportunity for the investigation into the relationship between spin fluctuations and SC without any effects of nematic fluctuations. Our ⁷⁵As nuclear magnetic resonance studies on CaK(Fe_1-xNi_x)₄As₄ (0≤ x ≤ 0.049) revealed that CaKFe₄As₄ is located close to a hidden hedgehog SVC AFM quantum-critical point (QCP). The magnetic QCP without nematicity in CaK(Fe_1-xNi_x)₄As₄ highlights the close connection of spin fluctuations and superconductivitymore »« less

Journal Article Sangeetha, N. S. ; Wang, L. -L. ; Smirnov, A. V. ; ... - Physical Review B

The compound SrCo₂As₂ with the body-centered tetragonal ThCr₂Si₂ structure is known to remain paramagnetic down to a temperature T = 0.05 K, but inelastic neutron scattering studies have shown that both ferromagnetic (FM) and antiferromagnetic (AFM) fluctuations occur in single crystals. Thus it is of interest to study how the magnetism evolves on doping SrCo₂As₂. Previous work on polycrystalline samples of Sr (Co_1-x Ni_x)₂ As₂ indicated the development of AFM order for 0 < x ≲ 0.3. Here we studied single crystals of Sr(Co_1-x Ni_x)₂ As₂ for 0 < x ≤ 1 and confirmed the occurrence of AFM order whichmore »« less

Low-temperature (22 K) irradiation with 2.5-MeV electrons, creating point defects affecting elastic scattering, was used to study the competition between stripe C-2 and tetragonal C-4 antiferromagnetic phases which exist in a narrow doping range around x = 0.25 in hole-doped Ba_1-xK_xFe₂As2. In nearby compositions outside of this range, at x = 0.22 and x = 0.19, the temperatures of both the concomitant orthorhombic/stripe antiferromagnetic transition T-C2 and the superconducting transition T-c are monotonically suppressed by added disorder at similar rates of about 0.1 K/mu Ω cm, as revealed through using resistivity variation as an intrinsic measure of scattering rate.
