Title: Polarization-dependent infrared reflectivity study of ${Sr}_{2.5} {Ca}_{11.5} {Cu}_{24} O_{41}$ under pressure: Charge dynamics, charge distribution, and anisotropy

Abstract

We present a polarization-dependent infrared reflectivity study of the spin-ladder compound Sr₂̣₅Ca₁₁̣₅Cu₂₄O₄₁ under pressure. The optical response is strongly anisotropic, with the highest reflectivity along the ladders/chains (E∥c) revealing a metallic character. For the polarization direction perpendicular to the ladder plane, an insulating behavior is observed. With increasing pressure the optical conductivity for E∥c shows a strong increase, which is most pronounced below 2000cm⁻¹. According to the spectral weight analysis of the E∥c optical conductivity the hole concentration in the ladders increases with increasing pressure and tends to saturate at high pressure. At ~7.5 GPa the number of holes per Cu atom in the ladders has increased by Δδ=0.09(±0.01), and the Cu valence in the ladders has reached the value +2.33. Thus, the optical data suggest that Sr₂̣₅Ca₁₁̣₅Cu₂₄O₄₁ remains electronically highly anisotropic up to high pressure, also at low temperatures.

Weak coupling of pseudoacoustic phonons and magnon dynamics in the incommensurate spin-ladder compound $S r_{14} C u_{24} O_{41}$

Journal Article Chen, Xi ; Bansal, Dipanshu ; Sullivan, Sean ; ... - Physical Review B

Intriguing lattice dynamics have been predicted for aperiodic crystals that contain incommensurate substructures. Here we report inelastic neutron scattering measurements of phonon and magnon dispersions in Sr₁₄Cu₂₄O₄₁, which contains incommensurate one-dimensional (1D) chain and two-dimensional (2D) ladder substructures. Two distinct pseudoacoustic phonon modes, corresponding to the sliding motion of one sublattice against the other, are observed for atomic motions polarized along the incommensurate axis. In the long wavelength limit, it is found that the sliding mode shows a remarkably small energy gap of 1.7–1.9 meV, indicating very weak interactions between the two incommensurate sublattices. The measurements also reveal a gappedmore »« less

Quasi-two-dimensional fluctuations in the magnetization of $L a_{1.9} C a_{1.1} C u_{2} O_{6 + δ}$ superconductors

Journal Article Shi, Xiaoya ; Dimitrov, I. K. ; Ozaki, Toshinori ; ... - Physical Review B

We report the results of magnetization measurements with the magnetic field applied along the c axis on superconducting La_1.9Ca_1.1Cu₂O_6+δ single crystals processed under ultrahigh oxygen pressure. Strong fluctuation effects were found in both low- and high-field regimes. Scaling analysis of the high-field magnetization data near the critical temperature (T_c = 53.5K) region reveals the characteristics of critical fluctuation behavior of quasi-two-dimensional (2D) superconductivity, described by Ginzburg-Landau theory using the lowest Landau level approximation. Low-field magnetic susceptibility data can be successfully explained by the Lawrence-Doniach model for a quasi-2D superconductor, from which we obtained the a b plane Ginzburg-Landau coherence lengthmore »« less

Temperature and polarization dependence of low-energy magnetic fluctuations in nearly optimally doped ${NaFe}_{0.9785} {Co}_{0.0215} As$

Journal Article Song, Yu ; Wang, Weiyi ; Zhang, Chenglin ; ... - Physical Review B

We use unpolarized and polarized neutron scattering to study the temperature and polarization dependence of low-energy magnetic fluctuations in nearly optimally doped NaFe_0.9785Co_0.0215As, with coexisting superconductivity (T_c ≈ 19 K) and weak antiferromagnetic order (T_N ≈ 30 K, ordered moment ≈ 0.02μ_B/Fe). A single spin resonance mode with intensity tracking the superconducting order parameter is observed, although energy of the mode only softens slightly upon approaching T_c. Polarized neutron scattering reveals that the single resonance is mostly isotropic in spin space, similar to overdoped NaFe_0.935Co_0.045As but different from optimal electron-, hole-, and isovalently doped BaFe₂As₂ compounds, all featuring an additionalmore »« less

Observation of the magnetic $C_{4}$ phase in ${Ca}_{1 - x} {Na}_{x} {Fe}_{2} {As}_{2}$ and its universality in the hole-doped 122 superconductors

Journal Article Taddei, K. M. ; Allred, J. M. ; Bugaris, D. E. ; ... - Physical Review B

Since its discovery in 2014, the magnetic tetragonal C₄ phase has been identified in a growing number of hole-doped 122 Fe-based superconducting compounds. Exhibiting a unique double-Q magnetic structure and a strong competition with both superconducting and magnetic order parameters, the C₄ phase and the conditions of its formation are of significant interest to understanding the fundamental mechanisms in these materials. Particularly, separating the importance of direct changes to the relative size of hole and electron pockets at the Fermi surface (achieved via charge doping) from the role of structural changes due to differences of ionic radii of dopants ismore »« less

Higgs Mode in the $d$ -Wave Superconductor ${Bi}_{2} {Sr}_{2} {CaCu}_{2} O_{8 + x}$ Driven by an Intense Terahertz Pulse

Journal Article Katsumi, Kota ; Tsuji, Naoto ; Hamada, Yuki I. ; ... - Physical Review Letters

We investigated the terahertz (THz)-pulse driven nonlinear response in the d-wave cuprate superconductor Bi₂Sr₂CaCu₂O_8+x (Bi2212) using a THz pump near-infrared probe scheme in the time domain. We have observed an oscillatory behavior of the optical reflectivity that follows the THz electric field squared and is strongly enhanced below T_c. The corresponding third-order nonlinear effect exhibits both A_1g and B_1g symmetry components, which are decomposed from polarization-resolved measurements. Comparison with a BCS calculation of the nonlinear susceptibility indicates that the A_1g component is associated with the Higgs mode of the d-wave order parameter.
