Description
High-temperature superconducting cuprates are an excellent model system to study the relationship between intertwined quantum phases. We aimed to influence the competition between superconductivity and charge order in La2-xSrxCuO4 (LSCO) by applying strain along the tetragonal c-axis direction, tuning the next-nearest neighbour hopping strength. X-ray diffraction measurements were performed at DESY to track charge order at different temperatures, dopings, and magnetic fields. Our results suggest, that c-axis strain drives the system closer to the state achieved with magnetic field. So, it stabilizes the charge ordered state while superconductivity is weakened, providing a fruitful approach to study the interplay between the two phenomena in the cuprates.
