Pressure-induced phase transitions in orthovanadates have led to interesting physical phenomena. The observed transitions usually involve large volume collapses and drastic changes in the electronic and vibrational properties of the materials. In some cases, the phase transitions implicate coordination changes in vanadium, which has important consequences in the physical properties of vanadates. In this Perspective, we explore the current knowledge of the behavior of MVO4 vanadates under compression. In particular, we summarize studies of the structural, vibrational, and electronic properties and a few illustrative examples of high-pressure research in the compounds of interest are discussed. A systematic understanding of the high-pressure behavior of MVO4 compounds is presented, putting the emphasis on results that could be relevant for practical applications. Recent advances and future challenges in the study of orthovanadates under extreme pressure will be reviewed, along with conclusions that could have consequences for the studies of related oxides. Some ideas on topics that may lead to exciting breakthroughs in the near future will be presented too.

原钒酸盐的高压晶体结构及其性质

原钒酸盐中压力引起的相变导致了有趣的物理现象。观察到的转变通常涉及材料的电子和振动特性的大体积坍塌和剧烈变化。在某些情况下,相变涉及钒的配位变化,这对钒酸盐的物理性质具有重要影响。在这个视角中,我们探索了 MVO4 钒酸盐在压缩下的行为的当前知识。特别是,我们总结了结构、振动和电子特性的研究,并讨论了一些对感兴趣的化合物进行高压研究的说明性例子。系统地了解 MVO4 化合物的高压行为,将重点放在可能与实际应用相关的结果上。将回顾极端压力下原钒酸盐研究的最新进展和未来挑战,以及可能对相关氧化物研究产生影响的结论。也将提出一些关于可能在不久的将来带来令人兴奋的突破的主题的想法。
