Popis: Substantial temperature dependent spatial modulation of the O and Cu NMR parameters of La 1.85 Sr 0.15 CuO 4 from 10 K to 300K are reported. The length scale of the modulations is only a few lattice distances. Analysis of the planar oxygen lineshape shows that modulations of the Knight shift and quadrupole coupling are correlated. The Cu spectra reveal a strong modulation of chemical shift. Similar results on other cuprates indicate universality of these phenomena.
