Abstract

We use resonant inelastic x-ray scattering to investigate charge-stripe correlations in La_1.675Eu_0.2Sr_0.125CuO4. By differentiating elastic from inelastic scattering, it is demonstrated that charge-stripe correlations precede both the structural lowerature tetragonal phase and the transport-defined pseudogap onset. The scattering peak amplitude from charge stripes decays approximately as T^-2 towards our detection limit. The in-plane integrated intensity, however, remains roughly temperature independent. Therefore, although the incommensurability shows a remarkably large increase at high temperature, our results are interpreted via a single scattering constituent. In fact, direct comparison to other stripe-ordered compounds (La_1.875Ba_0.125CuO₄, La_1.475Nd_0.4Sr_0.125CuO₄, and La_1.875Sr_0.125CuO₄) suggests a roughly constant integrated scattering intensity across all these compounds. Our results therefore provide a unifying picture for the charge-stripe ordering in La-based cuprates. As charge correlations in La_1.675Eu_0.2Sr_0.125CuO₄ extend beyond the lowerature tetragonal and pseudogap phase, their emergence heralds a spontaneous symmetry breaking in this compound.
