Using Neutron Resonance Imaging to Spatially Resolve the Strontium Distribution in LSCO Superconductor

Superconducting LSCO samples have shown broad transition temperature ranges, which is suspected to be caused by inhomogeneous strontium doping of the sample. Through the use of neutron resonance imaging we can spatially resolve the strontium and lanthanum concentrations in the sample, and directly see how it correlates with the spatial distribution of transition temperature. The information obtained will aid in the characterisation and production of high quality superconductors, such that the effect of inhomogeneous doping can be separated from other effects that need to be investigated.
