  • We discuss the crossover of the form of the Cu NMR spin echo decay at the onset of Cu wipeout in lanthanum cuprates. Experimentally, the echo decay undergoes a crossover from Gaussian to exponential form below the temperature where the Cu NMR intensity drops. The wipeout and the change in behavior both arise because the nuclei experience spatially inhomogeneous spin fluctuations at low temperatures. We argue that regions where the spin fluctuations remain fast are localized on length scales of order 1-2 lattice spacings. The inhomogeneity is characterized by the local activation energy E{sub a}(r); we estimate the functional formmore » of E{sub a}(r) for points where E{sub a}(r) {approx} 0.« less

  • We present 75As nuclear magnetic resonance spin-lattice and spin-spin relaxation rate data in Ba(Fe 1–xCo x) 2As 2 and Ba(Fe 1–xCu x) 2As 2 as a function of temperature, doping, and magnetic field. The relaxation curves exhibit a broad distribution of relaxation rates, consistent with inhomogeneous glassy behavior up to 100 K. The doping and temperature response of the width of the dynamical heterogeneity is similar to that of the nematic susceptibility measured by elastoresistance measurements. In this study, we argue that quenched random fields which couple to the nematic order give rise to a nematic glass that is reflectedmore » in the spin dynamics.« less

  • Nuclear magnetic resonance (NMR) data on Cu, apical and planar O in La{sub 1.85}Sr{sub 0.15}CuO{sub 4} are presented. Spin echo double resonance shows that the large Cu magnetic shift distribution is of short-length scale. Analysis of the O data reveals static modulations of the spin susceptibility with a spin-spin correlation function near zero. The Cu shift distribution is found to be of orbital origin. The full planar oxygen spectra show a correlated modulation of the electric field gradient with the spin susceptibility. Similar results on other cuprates indicate universality of these phenomena.
