Abstract

A quest for new materials with the potential for high-temperature superconductivity was guided by the structural features and compositions of recognized superconductors in a variety of material families. Specifically, new materials with layered structures have been targeted via high-temperature solid-state synthesis. The structures and phase-purity of the polycrystalline products were analyzed via Rietveld refinement using X-ray powder diffraction (XRPD) data. Magnetic Field Modulated Microwave Spectroscopy (MFMMS), which can selectively detect superconducting transitions with high sensitivity, was used in conjunction with zero field cooled (ZFC) and field-cooled (FC) vibrating sample magnetometry (VSM) to search for indications of superconductivity. High resolution synchrotron X-ray powder diffraction (SXRPD) complements MFMMS in the analysis of complex polycrystalline product mixtures, and the resulting information has further guided synthetic efforts.
