| 中文摘要 | The Cu-rich La2CuO4+delta ([La]:[Cu] = 2:1 + x) samples with 0 less than or equal to x less than or equal to 0.18 are characterized using X-ray diffraction, transmission electron microscopy and electron energy loss spectrum methods. The excess Cu is identified to occupy the La site and the maximum of such substitution, i.e., the maximum of excess Cu content, x, is examined to be about 0.06. From the magnetization measurements of the samples with different excess Cu, we find that the substitution of Cu for La can remarkably enhance the three-dimensional antiferromagnetic exchange interaction, thus, promoting electronic phase separation in La2CuO4+delta system with delta < 0.01.
