Article Synopsis
- The Ruddlesden-Popper bilayer nickelate LaNiO has been linked to high-temperature superconductivity (HTSC) under high pressure (over 14 GPa), but lacks clear diamagnetic signals due to low superconducting volume fractions.
- Research on Pr-doped LaPrNiO polycrystalline samples shows that Pr substitutions help create a nearly pure bilayer structure, mitigating the intergrowth of competing phases.
- At pressures above 11 GPa, a transition occurs, with HTSC developing further, achieving notable superconducting transition temperatures and confirming bulk HTSC through significant diamagnetic signals below 75 K at over 15 GPa.
A "palm" cubic-anvil pressure cell (PCAC) having an outer diameter of 60 mm, the smallest cubic-anvil cell to date, was fabricated to insert in a large-bore superconducting magnet. The pressure cell has a sample space of ϕ 2.5 × 1.
