چکیده
We present a theoretical expression for the spin-echo decay rate, 1/T2G, in the quantum-critical regime of square lattice quantum antiferromagnets. Our results are in good agreement with recent experimental data by Imai et al. [Phys. Rev. Lett. 71, 1254 (1993)] for La2CuO4. Typeset using REVTEX

Universal magnetic properties of La 2 − δ Sr δ CuO 4 at intermediate temperatures .
We present the theory of two-dimensional, clean quantum antiferromagnets with a small, positive, zero temperature (T ) stiffness ρs, but with the ratio kBT/ρs arbitrary. Universal scaling forms for the uniform susceptibility (χu), correlation length(ξ), and NMR relaxation rate (1/T1) are proposed and computed in a 1/N expansion and by Monté-Carlo simulations. For large kBT/ρs, χu(T )/T and Tξ(T...
متن کاملMeasurement of unique magnetic and superconducting phases in oxygen-doped high-temperature superconductors La(2-x)Sr(x)CuO(4+y).
We present a combined magnetic neutron scattering and muon spin rotation study of the nature of the magnetic and superconducting phases in electronically phase separated La(2-x)Sr(x)CuO(4+y), x=0.04, 0.065, 0.09. For all samples, we find long-range modulated magnetic order below T(N) is approximately equal to Tc=39 K. In sharp contrast to oxygen-stoichiometric La(2-x)Sr(x)CuO(4), we find that t...
متن کاملInhomogeneous low frequency spin dynamics in La(1.65)Eu(0.2)Sr(0.15)CuO(4).
We report Cu and La nuclear magnetic resonance measurements in the title compound that reveal an inhomogeneous glassy behavior of the spin dynamics. A low temperature peak in the La spin lattice relaxation rate and the "wipeout" of Cu intensity both arise from these slow electronic spin fluctuations that reveal a distribution of activation energies. Inhomogeneous slowing of spin fluctuations ap...

Slow antiferromagnetic dynamics in the low temperature tetragonal phase of La 2−x Sr x CuO 4 as revealed by ESR of Gd spin probes Abstract Measuring the ESR 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 2−x Sr x CuO 4. The data give evidence that at particular levels of Sr and Eu doping the frequ...
متن کاملSystematic (63)Cu NQR and (89)Y NMR study of spin dynamics in Y(1-z)Ca(z)Ba(2)Cu(3)O(y) across the superconductor-insulator boundary.
We demonstrate that the spin dynamics in underdoped Y(1-z)Ca(z)Ba(2)Cu(3)O(y) for y approximately equal to 6.0 exhibit qualitatively the same behavior to underdoped La(2-x)Sr(x)CuO(4) for an equal amount of hole concentration p = z/2 = x< or =0.11. However, a spin gap appears as more holes are doped into the CuO(2) plane by increasing the oxygen concentration to y approximately equal to 6.5 for...
