| 摘 要： | 以三氯化铬和硫粉为原料,采用常压化学气相沉积法(CVD)成功制备出了二维Cr_(2)S_(3)纳米片,并对Cr_(2)S_(3)纳米片表面形貌、晶体结构、宏观磁性等进行系统研究。结果表明:二维Cr_(2)S_(3)纳米片光学形貌以三角形为主,尺寸最大可达到156.8μm,厚度最小为2.59 nm(约2个单元晶胞厚);晶体结构为菱方相结构,类似于单斜NiAs型晶体结构;磁性测试表明:菱方相的二维Cr_(2)S_(3)低温下呈亚铁磁性,面内为磁易轴方向,其奈尔温度约等于120 K,75 K时饱和磁化强度最大;在空气中放置1个月后二维Cr_(2)S_(3)纳米片依然保持较好的磁性性能,是一种环境稳定的二维磁性材料。

| Abstract: | Two-dimensional Cr2S3 nanosheets were successfully prepared by using chromium trichloride and sulfur powder as raw materials with atmospheric pressure chemical vapor deposition (CVD), and the surface morphology, crystal structure, and macroscopic magnetic properties of Cr2S3 nanosheets were systematically investigated. The results show that the optical morphology of two-dimensional Cr2S3 nanosheets is mainly triangular, with the maximum size of 156.8 μm and the minimum thickness of 2.59 nm (about 2 unit-cell thickness); the crystal structure is rhombohedral phase structure, similar to monoclinic NiAs-type crystal structure; the magnetic test shows that the two-dimensional Cr2S3 in rhombohedral phase is ferromagnetic material at low temperature, with the magnetic easy axis direction in-plane, and its Néel temperature is about equal to 120 K. The saturation magnetization intensity is maximum at 75 K. The magnetic properties of two-dimensional Cr2S3 nanosheets remain very good after one month in air, and it is an environmentally stable two-dimensional magnetic material. |
