a The La2O3Fe2Se2 crystal structure. b X-ray diffraction pattern of La2O3Fe2Se2 single crystal with the corresponding Miller indices (00 l) in parentheses. The inset shows photo of a typical La2O3Fe2Se2 single crystal. c Temperature dependence of resistivity in La2O3Fe2Se2 single crystal under high pressure. An insulator-metal transition occurs near 40 GPa. d Enlarged area of the temperature dependence of resistivity for La2O3Fe2Se2 single crystal when entering the metallic state. The pink arrows indicate the kinks in the resistivity curves which is possibly related to the ferromagnetic transition.
