Measuring the electron spin resonance of Gd spin probes we have studied the magnetic properties of the copper oxide planes in the low-temperature tetragonal (LTT) phase of Eu-doped La{sub 2{minus}x}Sr{sub x}CuO{sub 4}. The data give evidence that at particular levels of Sr and Eu doping the frequency of the antiferromagnetic fluctuations {omega}{sub sf} in the LTT phase dramatically decreases at low temperatures by almost three orders of magnitude. However, no static magnetic order has been… 
Strong enhancement of spin fluctuations in the low-temperature tetragonal phase of antiferromagnetically ordered La2-x-yEuySrxCuO4
Measurements of the static magnetization, susceptibility and electron spin resonance (ESR) of Gd spin probes have been performed to study the properties of antiferromagnetically ordered
Phase transitions in the incoherent lattice fluctuations in YBa 2Cu3O7-δ
The growing body of experimental evidence for the existence of complex textures of charges and spins in the high-temperature superconductors has drawn attention to the so-called ‘stripe-phase’ model
High-field ESR studies of the quantum spin magnet CaCu2O3
We report an electron spin resonance (ESR) study of the s = 1/2 Heisenberg pseudo-ladder magnet CaCu2O3 in pulsed magnetic fields up to 40 T. At sub-terahertz frequencies we observe an ESR signal
Gd3+ electron spin resonance spectroscopy on LaO1 − xFxFeAs superconductors
We report an electron spin resonance (ESR) spectroscopy study on polycrystalline samples of the LaO1 − xFxFeAs (x = 0 and 0.1) compound with small levels of Gd doping (2% and 5%). The Gd ESR signal
Rare Earth Spin Dynamics in the Nd-Doped High-Tc Superconductor La2−xSrxCuO4
Inelastic magnetic neuron scattering experiments on the high-Te superconductor La2−x−ySrxNdyCuO4 were carried out. We investigated the relaxation behavior of the 4f moments for different Sr and Nd
Dzyaloshinsky-Moriya Spin Canting in the LTT Phase of La2-x-yEuySrxCuO4
The Cu spin magnetism in La2−x−yEuySrxCuO4 (x ≤ 0.17; y ≤ 0.2) has been studied by means of magnetization measurements in fields up to 14 Tesla. Our results clearly show that in the antiferromagnetic
Consequences of stripe order for the transport properties of rare earth doped La2−xSrxCuO4
Abstract We present a detailed study of the resistivity and the thermopower in the stripe ordered non superconducting low temperature tetragonal phase of rare earth (RE=Nd,Eu) doped La2−xSrxCuO4. The
How to detect fluctuating stripes in the high-temperature superconductors
We discuss fluctuating order in a quantum disordered phase proximate to a quantum critical point, with particular emphasis on fluctuating stripe order. Optimal strategies for extracting information
Chapter 191 Electron paramagnetic resonance in cuprate superconductors and in parent compounds
Publisher Summary Electron-paramagnetic-resonance (EPR) techniques are a valuable tool to study the local electronic and magnetic properties in high-TC superconductors and in the magnetically ordered
Nuclear-magnetic-resonance evidence for charge inhomogeneity in stripe ordered La(1.8-x)Eu0.2Sr(x)CuO4.
TLDR
These results are interpreted as microscopic evidence for a spatially inhomogeneous charge distribution, where the NMR signal from O sites in the domain walls of the spin density modulation are wiped out due to large hyperfine fields, and the remaining signal arises from the intervening Mott insulating regions.
