Title: Magnetic fluctuations and superconducting properties of ${CaKFe}_{4} {As}_{4}$ studied by ${}^{75}{As}$ NMR

Abstract

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. Nearly T independent behavior of the Knight shifts K is observed in the normal state, and a sudden decrease in K in the superconducting (SC) state suggests spin-singlet Cooper pairs. ⁷⁵As spin-lattice relaxation rates 1/T₁ show a power-law T dependence with different exponents for the two As sites. The isotropic antiferromagnetic spin fluctuations characterized by the wave vector q = (π, 0) or (0, π) in the single-iron Brillouin zone notation are revealed by 1/T₁T and K measurements. Such magnetic fluctuations are necessary to explain the observed temperature dependence of the ⁷⁵As quadrupole frequencies, as evidenced by our first-principles calculations. Finally, in the SC state, 1/T₁ shows a rapid decrease below T_c without a Hebel-Slichter peak and decreases exponentially at low T, consistent with anmore » s^± nodeless two-gap superconductor.« less

Volovik effect and Fermi-liquid behavior in the $s$ -wave superconductor ${CaPd}_{2} {As}_{2} : {}^{75}{As}$ NMR-NQR measurements

Journal Article Ding, Q. -P. ; Wiecki, P. ; Anand, V. K. ; ... - Physical Review B

The electronic and magnetic properties of the collapsed-tetragonal CaPd₂As₂ superconductor (SC) with a transition temperature of 1.27 K have been investigated by ⁷⁵As nuclear magnetic resonance (NMR) and nuclear quadrupole resonance (NQR) measurements. The temperature (T) dependence of the nuclear spin lattice relaxation rates (1/T₁) and the Knight shifts indicate the absence of magnetic correlations in the normal state. In the SC state, 1/T₁ measured by ⁷⁵As NQR shows a clear Hebel-Slichter (HS) peak just below T_c and decreases exponentially at lower T, confirming a conventional s-wave SC. Additionally, the Volovik effect, also known as the Doppler shift effect, hasmore »« less

Journal Article Torchetti, D. A. ; Fu, M. ; Christensen, D. C. ; ... - Physical Review. B, Condensed Matter and Materials Physics

We report comprehensive 77 Se NMR measurements on a single crystalline sample of the recently discovered FeSe-based high-temperature superconductor K x Fe 2 - y Se 2 ( T c = 33 K) in a broad temperature range up to 290 K. Despite deviations from the stoichiometric KFe 2 Se 2 composition, we observed 77 Se NMR line shapes as narrow as 4.5 kHz under a magnetic field applied along the crystal c axis, and found no evidence for co-existence of magnetic order with superconductivity. On the other hand, the 77 Se NMR line shape splits into two peaks withmore »« less

Pressure dependence of coherence-incoherence crossover behavior in ${KFe}_{2} {As}_{2}$ observed by resistivity and ${}^{75}{As}$ -NMR/NQR

Journal Article Wiecki, P. ; Taufour, V. ; Chung, D. Y. ; ... - Physical Review B

We present the results of ⁷⁵As nuclear magnetic resonance (NMR), nuclear quadrupole resonance (NQR), and resistivity measurements in KF_e2 As₂ under pressure (p). The temperature dependence of the NMR shift, nuclear spin-lattice relaxation time (T₁), and resistivity show a crossover between a high-temperature incoherent, local-moment behavior and a low-temperature coherent behavior at a crossover temperature (T*). T* is found to increase monotonically with pressure, consistent with increasing hybridization between localized 3d orbital-derived bands with the itinerant electron bands. No anomaly in T* is seen at the critical pressure p_c= 1.8 GPa where a change of slope of the superconducting (SC)more »« less

Suppression of ferromagnetic spin fluctuations in the filled skutterudite superconductor ${SrOs}_{4} {As}_{12}$ revealed by ${}^{75}{As}$ NMR-NQR measurements

Journal Article Ding, Q. -P. ; Nishine, K. ; Kawamura, Y. ; ... - Physical Review B

Motivated by the recent observation of ferromagnetic spin correlations in the filled skutterudite SrFe₄As₁₂ [Q.-P. Ding et al., Phys. Rev. B 98, 155149 (2018)], we have performed ⁷⁵As nuclear magnetic resonance (NMR) and nuclear quadrupole resonance (NQR) measurements to investigate the role of magnetic fluctuations in the newly discovered isostructural superconductor SrOs₄As₁₂ with a superconducting transition temperature of T_c ~ 4.8 K. Here, knight shift K determined by the NQR spectrum under a small magnetic field ( ≤ 0.5 T) is nearly independent of temperature, consistent with the temperature dependence of the magnetic susceptibility.

${}^{139}{La}$ NMR investigation of the charge and spin order in a ${La}_{1.885} {Sr}_{0.115} {CuO}_{4}$ single crystal

Journal Article Arsenault, A. ; Takahashi, S. K. ; Imai, T. ; ... - Physical Review B

¹³⁹La NMR is suited for investigations into magnetic properties of La₂CuO₄ -based cuprates in the vicinity of their magnetic instabilities, owing to the modest hyperfine interactions between ¹³⁹La nuclear spins and Cu electron spins. We report comprehensive ¹³⁹La NMR measurements on a single-crystal sample of high-T_c superconductor La 1.885 Sr 0.115 CuO₄ in a broad temperature range across the charge and spin order transitions (T charge ≃ 80 K, T neutron spin ≃ T_c = 30 K). From the high-precision measurements of the linewidth for the nuclear spin I_z = + 1 / 2 to -1/2 central transition, we show that paramagnetic line broadening sets in precisely at T charge due to enhanced spin correlations within the CuO₂ planes. Additional paramagnetic line broadening ensues below ~35 K, signaling that Cu spins in some segments of CuO₂ planes are on the verge of three-dimensional magnetic order. A static hyperfine magnetic field arising from ordered Cu moments along the ab plane, however, begins to develop only below Tmore »« less
