我们研究了独居石型SrCrO4在压缩状态下的电子和振动性质。该研究将以前研究的压力范围从26 GPa扩展到58 GPa。两个先前报道的相变的存在被证实在9和14 GPa，和两个新的相变被发现在35和48 GPa。这些转变涉及的振动和传输特性的几个变化与新的高压相具有导电性低于以前已知的阶段。未检测到SrCrO4的化学分解或金属化的证据。一个初步的解释报告的意见进行了讨论。
We studied the electronic and vibrational properties of monazite-type SrCrO4 under compression. The study extended the pressure range of previous studies from 26 to 58 GPa. The existence of two previously reported phase transitions was confirmed at 9 and 14 GPa, and two new phase transitions were found at 35 and 48 GPa. These transitions involve several changes in the vibrational and transport properties with the new high-pressure phases having a conductivity lower than that of the previously known phases. No evidence of chemical decomposition or metallization of SrCrO4 was detected. A tentative explanation for the reported observations is discussed.
