Description
We use synchrotron x-ray scattering from La1.8Sr0.2NiO4 and La1.925Sr0.075CuO4 to establish a direct relationship between carriers due to Sr doping and strong diffuse scattering. In the nickelate the scattering is peaked at the fourfold symmetric satellite positions (±δ,±δ,l), where the basal-plane coordinate δ varies with the out-of-plane coordinate l of the momentum transfer. A similar scattering pattern is observed in the cuprate but with smaller values for δ
