Absence of superconductivity and density-wave transition in ambient-pressure tetragonal La4Ni3O10 - Nature Communications

AbstractThe recent discovery of superconductivity in La3Ni2O7 and La4Ni3O10 under pressure stimulates intensive research interests. These nickelates crystallize in an orthogonal/monoclinic structure and have a density-wave transition at ambient pressure. The application of pressure triggers a transition to tetragonal structure (I4/mmm), which is believed to be a key prerequisite for the emergence of superconductivity.
