Scientific paper

Pulsed NQR at the frequencies of 28-33 MHz has been used to study copper NQR spectra in YBa{2}Cu{3}O{7}, TmBa{2}Cu{3}O{7} and Y{0.9}Pr{0.1}Ba{2}Cu{3}O{7} compounds at temperatures of 4.2-200K. Quantitative analysis of the spectra has shown that the "plane" Cu(2) spectra shape is well described by using a model of 1D correlations of charge and spin distribution in CuO{2} planes (stripe correlations). In the undoped superconductors the charge-spin stripe structure moves fast in the CuO{2} planes, but doping the YBa{2}Cu{3}O{7} lattice with praseodymium slows this motion down.
