摘　　要：稀土元素因其丰富的电子结构,表现出很多独特的物理化学性能,在光学、磁性和电学等领域具有巨大的应用价值。压力作为自然界中基本的热力学变量,可以引起结构相变以及新的亚稳态稀土化合物的合成,高压下稀土元素及其化合物表现出许多新奇的物理化学性能,如室温超导、铁磁半金属等。简要概述稀土元素及其化合物高压研究进展,包括压致相变、化学合成等,以及高压对其磁性、光学等物理性质的影响,展示了高压化学在稀土领域的应用前景。The applications of rare earth elements in optics, magnetics and electrics have been a subject of extensive research because of their unique physical and chemical properties arising from their abundant electronic structure. As a fundamental thermodynamic variable in nature, pressure can be used to induce phase transition and synthesis of new metastable rare earth compounds with exotic properties, such as near room-temperature superconductivity, half-metallic ferromagnetism, and many others. Here we focused on recent developments in state-of-the art experiments of the high-pressure studiesin rare earth element and compounds, including pressure-induced phase transition and high-pressure synthesis, in particular the effect of high pressure on the optical, magnetic and electronic properties. The perspective of high-pressure chemistry of rare earth was also proposed.
