Title: 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

Abstract

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 that interface superconductivity survives up to very high perpendicular fields, in excess of 40 T. Additionally, the critical magnetic field H_m(T) reveals an upward divergence with decreasing temperature, in line with vortex melting as in bulk superconducting cuprates.

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

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

Journal Article Guguchia, Z. ; Adachi, T. ; Shermadini, Z. ; ... - Physical Review B

High-pressure neutron powder diffraction, muon-spin rotation, and magnetization studies of the structural, magnetic, and the superconducting properties of the Ce-underdoped superconducting (SC) electron-doped cuprate system with the Nd₂ CuO₄ (the so-called T ' ) structure T ' - Pr_{1.3 - x} La_0.7 Ce_x CuO₄ with x = 0.1 are reported. A strong reduction of the in-plane and out-of-plane lattice constants is observed under pressure.

Nanoscale coherent intergrowthlike defects in a crystal of ${La}_{1.9} {Ca}_{1.1} {Cu}_{2} O_{6 + δ}$ made superconducting by high-pressure oxygen annealing

Journal Article Hu, Hefei ; Zhu, Yimei ; Shi, Xiaoya ; ... - Physical Review. B, Condensed Matter and Materials Physics

Superconductivity with T_c = 53.5 K has been induced in a large La₁.₉Ca₁.₁Cu₂O₆ (La-2126) single crystal by annealing in a high partial-pressure of oxygen at 1200°C. Using transmission electron microscopy (TEM) techniques, we show that a secondary Ca-doped La₂CuO₄ (La-214) phase, not present in the as-grown crystal, appears as a coherent “intergrowth” as a consequence of the annealing. A corresponding secondary superconducting transition near 13 K is evident in the magnetization measurement. In this study, electron energy loss spectroscopy (EELS) reveals a pre-edge peak at the O K edge in the superconducting La-2126 phase, which is absent in the as-grownmore »« less
