- W2028081005 abstract "Abstract We present an extensive nuclear magnetic resonance (NMR) and nuclear quadrupole resonance (NQR) study of the normal state (T>Tc) of an YBa1.93Sr0.07Cu3O6.92 single crystal (Tc=90 K). The NMR data is interpreted using a model for the imaginary part of the dynamical electron spin susceptibility χ″(q,ω) that is consistent with the inelastic neutron scattering (INS) experiments (carried out on the same sample investigated here): the q-dependence is assumed to be Gaussian (commensurate), with short and T independent coherence length ξ. This model enabled us to perform a quantitative analysis of the planar copper spin–lattice and spin–spin relaxation rates which evidenced that a spin pseudogap starts to open at T*≈130 K, confirming the INS results. Moreover, we show that the AF fluctuations contribution to yttrium relaxation is not negligible due to the dipolar coupling of the yttrium with the neighboring copper spins. The main signature of this feature is that a relation KααT1T=const does not hold for the yttrium site at higher temperatures. Our main conclusion is that, in order to explain the yttrium (and the planar oxygen) relaxation coherently with the INS results and the widely accepted one-band picture, the characteristic energy Γ0 of the spin dynamics near q=0 must be strongly T dependent, otherwise the one-band description is not feasible. All the NMR results are interpreted within the ionic model of the hyperfine Hamiltonian taking into account the anisotropy of the g-factor and the static spin susceptibility χs." @default.
