Absence of superconductivity and density-wave transition in ambient-pressure tetragonal La4Ni3O10
The recent discovery of superconductivity in La<sub>3</sub>Ni<sub>2</sub>O<sub>7</sub> and La<sub>4</sub>Ni<sub>3</sub>O<sub>10</sub> 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. Here, we report the first tetragonal nickelates La<sub>4</sub>Ni<sub>3</sub>O<sub>10</sub> microcrystals at ambient pressure. In tetragonal La<sub>4</sub>Ni<sub>3</sub>O<sub>10</sub>, transport measurements find that both density-wave and superconducting transitions are absent up to 160 GPa, indicating a robust tetragonal metallic ground state. Meanwhile, density functional theory calculations reveal a considerable contribution of d<sub>z2</sub> orbital to the Fermi surface. The concurrent absence of density-wave state and high-pressure superconductivity in tetragonal La<sub>4</sub>Ni<sub>3</sub>O<sub>10</sub> suggests that the density-wave state instead of tetragonal structure is crucial for the superconductivity in nickelates under pressure. Our findings impose important constraints on the mechanism of pressure-induced superconductivity in nickelates.
