| 摘 要： | 采用脉冲激光气相沉积（PLD）技术在MgO（100）衬底上生长了Co/BaTiO3纳米复合薄膜，利用原子力显微镜、透射电镜、X射线衍射（XRD）及Raman光谱等测试分析手段对Co/BaTiO3纳米复合薄膜进行测试分析。结果表明：薄膜表面均匀、致密，具有原子尺度的光滑性；Co纳米晶粒呈单分散、均匀分散在沿C轴呈单取向生长的BaTiO3单晶基体中；随着掺杂Co含量的增高，BaTiO3的Raman峰的峰强随之增大。 |

| Abstract: | Nano Co/BaTiO3 compound thin films on single crystal magnesia(100) are fabricated by pulsed laser deposition. The characteristics of films are investigated by atomic force microscopy(AFM), transmission microscopy(TEM) X-ray diffraction (XRD) and Raman spectra techniques. The results show that the surface of the films is uniform, compact and smooth. The Co nano particles are well dispersed in the BaTiO3 matrix, which is single crystal with C-axis orientation and tetragonal structure. With the increase of Co component, the intensity of Raman peaks of BaTiO3 matrix gets enhanced. |
| Keywords: | Pulse laser deposition Co/BaTiO3 nano compound thin films Nano particles Raman spectra |
