Pressure-Induced Superconductivity In Polycrystalline La3Ni2O7-δ

We synthesized polycrystalline La3Ni2O7-δ (δ ≈ 0.07) samples by using the sol-gel method without postannealing under high oxygen pressure, and then measured temperature-dependent resistivity under various hydrostatic pressures up to 18 GPa by using the cubic anvil and two-stage multianvil apparatus....
