Abstract
We report a comprehensive study of the uniaxial stress response of charge density wave (CDW) correlations in detwinned single crystals of the high-temperature superconductor YBa2Cu3O6+x (YBCO6+x) with 0.40≤x≤0.93 (hole-doping levels 0.072≤p≤0.168) by means of Cu L3-edge resonant energy-integrated x-ray scattering (REXS). We show that the influence of uniaxial stress is strongly doping dependent: the quasi-two-dimensional CDW is enhanced by in-plane uniaxial stress in a wide hole-doping range (0.45≤x≤0.80), but only barely affected in the most underdoped and optimally doped samples (x=0.40 and 0.93), where the CDW correlation length is minimal. A stress-induced three-dimensionally long-range-ordered (3D) CDW was observed only in YBCO6.50 and YBCO6.67. The temperature dependence of the 3D CDW clearly indicates a strong competition with superconductivity. Based on the systematic strain-, doping-, and temperature-dependent REXS measurements reported here, we discuss the relationship between charge order and superconductivity in YBCO6+x and other cuprates.
