Extended Data Fig. 8: Hall resistivity ρxy (H) at 80 K under various pressures.
From: High-temperature superconductivity with zero resistance and strange-metal behaviour in La3Ni2O7−δ
ρxy(H) for La3Ni2O7−δ sample S1-3 from 7.5 GPa to 19.4 GPa, where the red dashed lines show fits to a linear magnetic field dependence.
