Superconductivity in infinite layer nickelates — •Harold Hwang — Stanford University and SLAC National Accelerator Laboratory

Ever since their discovery, superconductivity in cuprates has motivated the search for materials with analogous electronic or atomic structure. Here we present how soft chemistry approaches can be used to synthesize superconducting infinite layer nickelates from their perovskite precursor phase [1], using topotactic reactions. We will discuss our preliminary understanding of aspects that are similar and different from the cuprates, as well as initial exploration of the doping dependence of the phase diagram.
