Abstract/Contents

Abstract: In this thesis we design, perform, and report the results of a scanning SQUID experiment that studies light’s effect on thin films of Lanthanum Barium Copper Oxide (LBCO), the first discovered high temperature superconductor. This work builds off of the research of previous scientists who studied photo-enhanced superconductivity in Yttrium Barium Copper Oxide, another cuprate like LBCO. With scanning SQUID, we are able to not only measure, but spatially resolve changes in LBCO’s diamagnetic response due to illumination. This research could help us understand the mechanism behind photo-induced effects in certain superconductors as well as offer an insight into the microscopic origin of high temperature superconductivity.
