| 摘 要： | 采用磁控溅射法在Si(100)衬底上制备了掺碳氧化铟(In2O3:C)薄膜,溅射过程分别在衬底温度为室温和550℃的条件下进行。通过测试所制In2O3:C薄膜的XRD谱和磁化曲线,研究了In2O3:C薄膜的结构和铁磁性能,并探讨了其铁磁性的起源。结果显示,随着含碳量的增加,In2O3:C薄膜的饱和磁化强度先增大后减小;此外,氧空位缺陷浓度高的样品其铁磁性也更强,这表明氧空位缺陷与In2O3:C薄膜的铁磁性起源有直接的关系。

| Abstract: | Carbon-doped In2O3(In2O3:C) thin films were prepared on Si(100) substrates by magnetron sputtering technique.The deposition progresses were carried out at substrate temperatures of room temperature and 550 ℃,respectively.The structure and ferromagnetic properties of prepared In2O3:C thin films were characterized by XRD and magnetization curves,and the origin of ferromagnetism of In2O3:C thin films was discussed accordingly.The results show that,with the increasing of carbon concentration,the saturation magnetization of In2O3:C thin films increases first,and then decreases;in addition,the ferromagnetic signals are found stronger in those samples with higher concentration of oxygen vacancy,which suggests that the origin of ferromagnetism is directly related to the oxygen vacancies in In2O3:C thin films. |
