Abstract

A charge modulation has recently been reported in (Y,Nd)Ba $_{2}$ Cu $_{3}$ O $_{6 + x}$ [Ghiringhelli {\em et al.} Science 337, 821 (2013)]. Here we report Cu $L_{3}$ edge soft x-ray scattering studies comparing the lattice modulation associated with the charge modulation in YBa $_{2}$ Cu $_{3}$ O $_{6.6}$ with that associated with the well known charge and spin stripe order in La $_{1.875}$ Ba $_{0.125}$ CuO $_{4}$ . We find that the correlation length in the CuO $_{2}$ plane is isotropic in both cases, and is $259 \pm 9$ Åfor La $_{1.875}$ Ba $_{0.125}$ CuO $_{4}$ and $55 \pm 15$ Åfor YBa $_{2}$ Cu $_{3}$ O $_{6.6}$ . Assuming weak inter-planar correlations of the charge ordering in both compounds, we conclude that the order parameters of the lattice modulations in La $_{1.875}$ Ba $_{0.125}$ CuO $_{4}$ and YBa $_{2}$ Cu $_{3}$ O $_{6.6}$ are of the same order of magnitude.
