Title: Spin pseudogap in the $S = \frac{1}{2}$ chain material ${Sr}_{2} {CuO}_{3}$ with impurities

Abstract

Here, the low-energy magnetic excitation spectrum of the Heisenberg antiferromagnetic S = 1/2 chain system Sr₂CuO₃ with Ni and Ca impurities is studied by neutron spectroscopy. In all cases, a defect-induced spectral pseudogap is observed and shown to scale proportionately to the number of scattering centers in the spin chains.

Unusual magnetic excitations in the weakly ordered spin- $\frac{1}{2}$ chain antiferromagnet ${Sr}_{2} {CuO}_{3}$ : Possible evidence for Goldstone magnon coupled with the amplitude mode

Journal Article Sergeicheva, E. G. ; Sosin, S. S. ; Prozorova, L. A. ; ... - Physical Review B

We report on an electron spin resonance (ESR) study of a nearly one-dimensional (1D) spin-1/2 chain antiferromagnet, Sr₂CuO₃, with extremely weak magnetic ordering. The ESR spectra at T > T_N, in the disordered Luttinger-spin-liquid phase, reveal nearly ideal Heisenberg-chain behavior with only a very small, field-independent linewidth, ~1/T. In the ordered state, below T_N, we identify field-dependent antiferromagnetic resonance modes, which are well described by pseudo-Goldstone magnons in the model of a collinear biaxial antiferromagnet. Additionally, we observe a major resonant mode with unusual and strongly anisotropic properties, which is not anticipated by the conventional theory of Goldstone spin waves.more »« 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

Single-ion properties of the $S_{eff}$ = $\frac{1}{2}$ XY antiferromagnetic pyrochlores $Na A^{'} {Co}_{2} F_{7}$ ( $A^{'} = {Ca}^{2 +}, {Sr}^{2 +}$ )

Journal Article Ross, Kathryn A. ; Brown, J. M. ; Cava, R. J. ; ... - Physical Review B

The antiferromagnetic pyrochlore material NaCaCo₂F₇ is a thermal spin liquid over a broad temperature range (≈140 K down to T_F=2.4 K), in which magnetic correlations between Co²⁺ dipole moments explore a continuous manifold of antiferromagnetic XY states. The thermal spin liquid is interrupted by spin freezing at a temperature that is ~2% of the mean-field interaction strength, leading to short-range static XY clusters with distinctive relaxation dynamics. Here we report the low-energy inelastic neutron scattering response from the related compound NaSrCo₂F₇, confirming that it hosts the same static and dynamic spin correlations as NaCaCo₂F₇. We then present the single-ion levelsmore »« less

Parallel spin stripes and their coexistence with superconducting ground states at optimal and high doping in ${La}_{1.6 - x} {Nd}_{0.4} {Sr}_{x} {CuO}_{4}$

Journal Article Ma, Qianli ; Rule, Kirrily C. ; Cronkwright, Zachary W. ; ... - Physical Review Research

Three-dimensional, commensurate long-range magnetic order in La₂CuO₄ quickly evolves to quasi-two-dimensional, incommensurate correlations upon doping with mobile holes, and superconductivity follows for x as small as 0.05 in the La_2-xSr_x/Ba_xCuO₄ family of superconductors. The onset of superconductivity in these systems is known to be coincident with a remarkable rotation of the incommensurate spin order from “diagonal stripes” below x = 0.05 to “parallel stripes” above. However, little is known about the spin correlations at optimal and high doping levels, around and beyond the proposed quantum critical point for the pseudogap phase, p*.
