Single-crystal structural phase diagram of stoichiometric bilayer nickelate La3Ni2O7 under hydrostatic pressure

Misaki Sasaki, Zhehong Liu, Takeshi Hara +12

The study determines the pressure‑temperature phase diagram of stoichiometric La₃Ni₂O₇ single crystals, revealing a direct transition from a charge‑ordered orthorhombic Am2m struct…
