英文摘要 | The thermodynamic stability and thermal expansion of pure-phase BiFeO3 multiferroic are studied using in-situ high temperature X-ray diffraction (HT-XRD), and high temperature Raman spectroscopy (HT-Raman). BiFeO3 keeps its rhombohedral structure with space group of R3c in heating process. However, minor BiFeO3 could decompose to Bi2Fe4O9 and Bi25FeO39 in cooling process, which may be induced by its oxygen octahedron tilt distortion. In addition, the thermal expansion coefficients of BiFeO3 are also investigated, showing an isotropic and positive behavior. These results are further confirmed by Raman spectrum analysis. This work may benefit for the preparation of pure-phase BiFeO3. |
