Structual Investigation of La2-xSrxCuO4+y

Following staging as a function of temperature

The high-temperature superconductor La(2-x)Sr(x)CuO(4+y) was discovered almost three decades ago, but the mechanisms behind the superconductivity in the material  are still not fully understood. This thesis adds a small piece to the enormous puzzle of solving high-temperature superconductivity.

X-rays and neutrons have been used to investigate the superstructure known as staging, and temperature dependent results for four different samples will be presented and compared to results for similar compounds from literature.
