| 摘 要： | 本文首次报道了在0~3.21 GPa压力范围内MnF2的高压Raman光谱，结果表明压力在1.32 GPa附近，MnF2发生了一次结构相变，晶胞中氟原子构成的八面体没有解体。在3.21 GPa下，Raman谱带消失，表明又有一次结构相变发生。

| Abstract: | High-pressure Raman spectra of MnF2 are reported Tor the first time. The results show that MnF2 undergoes a structural transition at 1.32GPa, though the octahedron consisting of 8-fluorine atoms in the cell does not disintegrate due to the transition. No Raman peaks can be seen in the spectrum taken at 3.21 GPa,dempnstrating that MnF2 undergoes probably another structure phase transition. |
