We use single crystal Cu NMR techniques to revisit the early Cu NQR signature of charge order observed for La1.875Ba0.125CuO4 (Tc = 4 K) [A. W. Hunt et al., Phys. Rev. Lett. 82, 4300 (1999)]. We show that the growth of spin correlations is accelerated below ∼ 80 K, where the inverse Laplace transform (ILT) T1 analysis of the La NMR spin-lattice relaxation curve recently uncovered emergence of the slow components in the lattice and/or charge fluctuations [P. M. Singer et al., 101, 174508 (2020…

Stripe order, depinning, and fluctuations in La$_{1.875}$Ba$_{0.125}$CuO$_{4}$ and La$_{1.875}$Ba$_{0.075}$Sr$_{0.050}$CuO$_{4}$

We present a neutron scattering study of stripe correlations measured on a single crystal of La$_{1.875}$Ba$_{0.125}$CuO$_{4}$. Within the low-temperature-tetragonal (LTT) phase, superlattice peaks

Revisiting Cu 63 NMR evidence for charge order in superconducting La 1.885 Sr 0.115 CuO 4

Until recently, many authors remained skeptical about the presence of charge order in superconducting cuprates. As early as 1999, Hunt $e\phantom{\rule{0}{0ex}}t$ $a\phantom{\rule{0}{0ex}}l$. [Phys.

NMR measurement of the exchange coupling between Cu(2) atoms in YBa2Cu3O7- delta (Tc=90 K).

The authors demonstrate the existence of a strong indirect spin-spin coupling between Cu(2) nuclei, and show that it can be explained using a model in which the Cu( 2) atoms possess electronic magnetic moments which are exchange coupled to one another.

Similar glassy features in the L 139 a NMR response of pure and disordered La1.88 Sr0.12 CuO4

High ${T}_{c}$ superconductivity in ${\text{La}}_{2\ensuremath{-}x}{\text{Sr}}_{x}{\text{CuO}}_{4}$ coexists with (striped and glassy) magnetic order. Here, we report NMR measurements of the

Evidence for unusual superconducting correlations coexisting with stripe order in La 1.875 Ba 0.125 CuO 4

We present new x-ray and neutron-scattering measurements of stripe order in ${\text{La}}_{1.875}{\text{Ba}}_{0.125}{\text{CuO}}_{4}$, along with low-field susceptibility, thermal conductivity, and

Charge density wave fluctuations in La2-x Srx CuO4 and their competition with superconductivity

We report hard (14 keV) x-ray diffraction measurements on three compositions (x=0.11,0.12,0.13) of the high-temperature superconductor La2-xSrxCuO4. All samples show charge-density-wave (CDW) order

Cu nuclear magnetic resonance study of charge and spin stripe order in La1.875Ba0.125CuO4

In this paper, we present a Cu nuclear magnetic/quadrupole resonance study of the charge stripe ordered phase of LBCO, with detection of previously unobserved (“wiped-out”) signal. We show that

63Cu Nuclear Spin-Lattice Relaxation Study for Low-Temperature Structural Transition in (La1-xBax)2CuO4 around x=0.06

The nuclear spin-lattice relaxation rate 1/ T 1 of 63 Cu was measured in the range from 1.5 to 300 K for x =0.0625 and x =0.08 in (La 1- x Ba x ) 2 CuO 4 . In the high-temperature tetragonal (HTT)

Low frequency spin dynamics in undoped and Sr-doped La2CuO4.

For Sr-doped samples, it is found that [ital d] spins exhibit the characteristic behavior expected for a local moment system even for the highest-[ital T][sub [ital c]] phase La[sub 1.85]Sr[sub 0.15]CuO[sub 4], and cross over to an itinerant regime before superconductivity sets in.

Spin-spin correlation in the quantum critical regime of La2CuO4.

The finding that the ratio [sup 63]Cu nuclear spin echo decay rate 1/[ital T/sub 1]/[sup 63][ital T][sub 2[ital G]], is temperature independent, gives clear evidence for quantum critical scaling.
