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

Abstract

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 length of this system, ξ_ab(0) = 11.8 ± 0.9 Å . The coherence length along the c axis, ξ_c(0), is estimated to be about 1.65 Å, which is in between those of 2D cuprate systems, such as Bi₂Sr₂Ca₂Cu₃O₁₀ and Bi₂Sr₂CaCu₂O₈, and quasi-three-dimensional (3D) cuprate systems, such as overdoped La_2-xSr_xCuO₄ and YBa₂Cu₃O_7-δ. Our studies suggest a strong interplay among the fluctuation effects, dimensionalities, and the ratios of the interlayer Cu-O plane spacing, s , to the c-axis coherence lengths. A high s/ξ_c(0) was observed in the high-pressure oxygenated La_1.9Ca_1.1Cu₂O_6+δ, and that apparently drives this system to behave more like a quasi-2D superconductor.

Atomic-layer-resolved composition and electronic structure of the cuprate $B i_{2} S r_{2} CaC u_{2} O_{8 + δ}$ from soft x-ray standing-wave photoemission

Journal Article Kuo, Cheng-Tai ; Lin, Shih-Chieh ; Conti, Giuseppina ; ... - Physical Review B

A major remaining challenge in the superconducting cuprates is the unambiguous differentiation of the composition and electronic structure of the CuO₂ layers and those of the intermediate layers. The large c axis for these materials permits employing soft x-ray (930.3 eV) standing wave (SW) excitation in photoemission that yields atomic layer-by-layer depth resolution of these properties. Applying SW photoemission to Bi₂Sr₂CaCu₂O_8+δ yields the depth distribution of atomic composition and the layer-resolved densities of states. We detect significant Ca presence in the SrO layers and oxygen bonding to three different cations. The layer-resolved valence electronic structure is found to be stronglymore »« less

${}^{139}{La}$ 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

Highly dispersive magnons with spin-gap-like features in the frustrated ferromagnetic $S = \frac{1}{2}$ chain compound ${Ca}_{2} Y_{2} {Cu}_{5} O_{10}$ detected by inelastic neutron scattering

Journal Article Matsuda, Masaaki ; Ma, Jie ; Garlea, Vasile O. ; ... - Physical Review B

In this paper, we report inelastic neutron scattering experiments in Ca₂Y₂Cu₅O₁₀ and map out the full one-magnon dispersion which extends up to a record value of 53 meV for frustrated ferromagnetic (FM) edge-sharing CuO₂ chain (FFESC) cuprates. A homogeneous spin-1/2 chain model with a FM nearest-neighbor (NN), an antiferromagnetic (AFM) next-nearest-neighbor (NNN) inchain, and two diagonal AFM interchain couplings (ICs) analyzed within linear spin-wave theory (LSWT) reproduces well the observed strong dispersion along the chains and a weak one perpendicularly. The ratio α=|J_a2/J_a1| of the FM NN and the AFM NNN couplings is found as ~0.23, close to the critical point α_c=1/4 which separates ferromagnetically and antiferromagnetically correlated spiral magnetic ground states in single chains, whereas α_c>0.25 for coupled chains is considerably upshifted even for relatively weak IC. Although the measured dispersion can be described by homogeneous LSWT, the scattering intensity appears to be considerably reduced at ~11.5 and ~28 meV. The gaplike feature at 11.5 meV is attributed to magnon-phonon coupling whereas based on density matrix renormalization group simulations of the dynamical structure factor the gap at 28 meV is considered to stem partly from quantum effects due to the AFM IC. Another contribution to that gap is ascribed to the intrinsic superstructure from the distorting incommensurate pattern of CaY cationic chains adjacent to the CuO₂ ones. It gives rise to nonequivalent CuO₄ units and Cu-O-Cu bond angles Φ and a resulting distribution of all exchange integrals. The J's fitted by homogeneous LSWT are regarded as average values. The record value of the FM NN integral J₁=24 meV among FFESC cuprates can be explained by a nonuniversal Φ(≠90°) and Cu-O bond length dependent anisotropic mean direct FM Cu-O exchangemore »« less

Magnetic field dependence of high- $T_{c}$ interface superconductivity in $L a_{1.55} S r_{0.45} Cu O_{4} / L a_{2} Cu O_{4}$ heterostructures

Journal Article Gasparov, V. A. ; Drigo, L. ; Audouard, A. ; ... - Physical Review B

Heterostructures made of a layer of a cuprate insulator La₂CuO₄ on the top of a layer of a nonsuperconducting cuprate metal La_1.55Sr_0.45CuO₄ show high-T_c interface superconductivity confined within a single CuO₂ plane. Given this extreme quasi-two-dimensional quantum confinement, it is of interest to find out how interface superconductivity behaves when exposed to an external magnetic field. With this motivation, we have performed contactless tunnel-diode-oscillator-based measurements in pulsed magnetic fields up to 56 T as well as measurements of the complex mutual inductance between a spiral coil and the film in static fields up to 3 T. Remarkably, we observe thatmore »« less

Quasi-two-dimensional Bose-Einstein condensation of spin triplets in the dimerized quantum magnet ${Ba}_{2} {CuSi}_{2} O_{6} {Cl}_{2}$

Journal Article Okada, Makiko ; Tanaka, Hidekazu ; Kurita, Nobuyuki ; ... - Physical Review B

We synthesized single crystals of composition Ba₂CuSi₂O₆Cl₂ and investigated their quantum magnetic properties. The crystal structure is closely related to that of the quasi-two-dimensional (2D) dimerized magnet BaCuSi₂O₆ also known as Han purple. Ba₂CuSi₂O₆Cl₂ has a singlet ground state with an excitation gap of Δ/k_B = 20.8 K. The magnetization curves for two different field directions almost perfectly coincide when normalized by the g factor except for a small jump anomaly for a magnetic field perpendicular to the c axis. The magnetization curve with a nonlinear slope above the critical field is in excellent agreement with exact-diagonalization calculations based onmore »« less
