Stripe and spin dynamics in hole doped La2NiO4, La2CuO4, Bi2Sr2CaCu2O8 andelectron doped Nd1.85Ce0.15CuO4 seen by nuclear resonance

Using new resonance results, we investigate the relation between the charge and spin ordering features seen by a.o. neutron scattering and ARPES, and the NMR/NQR signal intensities (wipe-out effects), relaxation rates and lin e shapes in hole doped La2NiO4, La2CuO4, Bi2Sr2CaCu2O8 and electron doped N dCeCuO4. We indicate what is understood and which questions are still open, with especially a focus on the observation that the wipe out effects happe n in both hole and electron doped systems and continue down to the lowest m easured temperatures. The latter feature might be the signature of a glassy dynamics of an entirely new kind, associated with the special nature of st ripe order.
