Abstract
This project will gauge the potential of Ag2+ cation in new superconducting and exotic magnetic materials. Specialized experimental methods and techniques derived from inorganic fluorine chemistry and solid-state chemistry will be applied to tackle a novel and highly-challenging study which holds the potential to bring a breakthrough in science – the discovery of a new, Ag2+-based, family of superconductors. Very recently, Ag2+-F-based materials have been recognized as analogues to Cu2+-O-based compounds. The Ag2+ cation is uncommon and hard to stabilize and its chemistry and thermodynamic stability is limited to compounds where this cation is found in a fluorine environment. Moreover, the Ag2+ fluorides are very reactive making the handling and investigation of such compounds a very challenging process. This project proposes a unique team that blends rare skills of synthetic fluorine chemistry, solid-state chemistry, and magnetism to try to advance the chemistry and materials science of Ag2+. We first plan to synthesize high-quality AgF2 in house, as well as other binary fluorides precursors and use these for syntheses of a series of fluoridoargentates(II). Several composition spaces will be explored (e.g., Y-Ba-Ag-F, Hg-Ba-Ca-Ag-F), inspired by analogies with the cuprate superconducting systems. These systems will be studied by a multi-pronged synthetic approach, namely in solution, high-temperature solid-state route, and mechanochemically. The structure-property studies will be employing a combination of methods, including X-ray diffraction, magnetic measurements, and vibrational spectroscopies, and resonance techniques. The results obtained in this study would be of paramount importance for fundamental science and for validation of computational results that predict superconductivity and exotic magnetic properties in this family of compounds.
