Extended Data Fig. 7: Crystal structure, Laue measurements, and magnetic susceptibility of single crystalline La3Ni2O7−δ.
From: High-temperature superconductivity with zero resistance and strange-metal behaviour in La3Ni2O7−δ
a, Crystal structure. b, c, d, X-ray Laue pattern corresponding to the [001] direction, where simulations of the orthorhombic structure with space group Amam are shown by red spots. e, f, g Temperature dependence of the magnetic susceptibility χ(T) of samples S1-S3 measured in a magnetic field of 0.4 T applied perpendicular to the c axis. The temperature dependence of the magnetic susceptibility of the three samples are also displayed in this figure for fields perpendicular to the c-axis, which show similar behaviour, and also correspond well to the data in Ref. 29 for this field direction.
