| 摘要: |
| 我们在9T的磁场下成功合成了Sr2IrO4 样品，并且研究了它的结构和磁性。尽管样品的晶体结构与在零场下合成的样品相比没有改变，高分辨透射电镜像显示出电子云的分布发生了变化。在暗区，态密度增强引起了样品的磁性发生改变。我们提出9T的强磁场有利于生长出更纯相的样品。 |

| Abstract: |
| Sr2IrO4 has been successfully synthesized under the magnetic field with 9 T, and the structural and magnetic properties were characterized. Although its structure and crystal lattice are the same with the sample synthesized under 0 T, HRTEM reveals that the distribution of electron cloud is changed. The increased density of states in the dark regions leads to the differences in magnetism from the sample synthesized under 0 T. Our finding indicates that the magnetic field of 9 T could be more favorable to the growth of pure phase. |
