| 摘 要： | 利用金刚石对顶压砧，对钙钛矿型金属锰化物Mn3Zn0.8Ni0.2N进行了原位高压同步辐射角散X射线衍射研究。研究表明，在0~29.9 GPa的压力区间内，样品没有发生结构相变，因而在该压力下样品的物性变化并非由结构相变所导致。卸压以后，样品的特征峰都回到了初始位置。通过Birch-Murnaghan方程，拟合得到了样品的体弹模量为86.5 GPa。 |
| 关 键 词： | 反钙钛矿结构 高压 同步辐射 体弹模量 |

| Abstract: | The structural stability of Mn3Zn0.8Ni0.2N was investigated up to 29.9 GPa by in situ angle dispersive X-ray diffraction using synchrotron radiation source and a diamond anvil cell. No structural phase transition was observed in the pressure range of 0-29.9 GPa. This result indicates that the changes in the physical properties of Mn3Zn0.8Ni0.2N under pressure are not induced by structural phase transition. Through fitting the Birch-Murnaghan equation, we obtain the bulk modulus B0= 86.5 GPa for Mn3Zn0.8Ni0.2N, assuming its first order derivative B′0=4 at ambient pressure. |
