## Description

- description: 'La₃Ni₂O₇ was recently discovered to exhibit superconductivity below
    Tc ≃ 80 K under high pressures above ~14 GPa. Owing to its relatively high transition
    temperature and structural similarity to high-Tc cuprates, this finding immediately
    stimulated intense interest and led to the subsequent observation of superconductivity
    in La₄Ni₃O₁₀. These materials belong to the Ruddlesden–Popper series, composed
    of double- and triple-layered NiO₂ square lattices separated by LaO rock-salt
    layers. Research has rapidly progressed along three closely related directions:
    broadening the chemical diversity of the compounds, enhancing Tc through elemental
    substitution, and clarifying the superconducting pairing mechanism. Among these,
    elucidating the mechanism remains particularly challenging because key experiments
    must be performed under high pressure. Therefore, developing nickel oxides that
    become superconducting at lower pressures, ideally at ambient pressure, is a central
    objective, as it would enable wider chemical tuning and more detailed physical
    characterization. This review summarizes the current status of the field, with
    emphasis on sample synthesis and structural characterization, while also outlining
    the reported electronic properties.'
