    Abstract text

    In all cuprate superconducting compounds, hole doping of the CuO2 plane disrupts the magnetic order of the pristine Mott insulating state while retaining antiferromagnetic superexchange interactions. These interactions are hypothesized to mediate the high temperature superconductivity. Here we discuss recent developments in scanned Josephson tunnel microcopy (SJTM) which allow direct, atomic scale, visualization of the strongly correlated superfluid found in these systems as well as the magnetic properties. The research objective is to thereby visualize the influence on both the strong correlation pairing and magnetic fluctuations of nanoscale perturbations such as crystal defects and impurities. This could reveal the connection between strong correlation pairing and magnetic fluctuations at the atomic scale in the cuprates.
