ARPES on Coherently Strained Ruddelsden-Popper Nickelate Thin Films
Part of MAR-B32 Superconducting Nickelate Compounds I
Since the discovery of high-Tc superconductivity in the Ruddelsden-Popper (RP) Nickelates La3Ni2O7 and La4Ni3O10 under high hydrostatic pressure, there has been great interest in determining the mechanism for this superconductivity. A key difference with cuprate superconductivity is the presence of dz2 bands near the Fermi energy in addition to the dx2-y2 bands, so finding a way to explore these under pressure is critical. It has been shown that the effects of high hydrostatic pressure can be mimicked by in-plane strain, which can be accomplished via epitaxial thin-film growth on various substrates. Here we report ARPES measurements collected on a series of substrate-strained RP nickelate thin films under both tensile and compressive strain. Quantitative changes are observed in several bands near the Fermi level.
