The effects of external pressure on a high-performing dysprosocenium single-molecule magnet are investigated using a combination of X-ray diffraction, magnetometry and theoretical calculations. The effective energy barrier () decreases from 1300 cm at ambient pressure to 1125 cm at 3 GPa. Our results indicate that compression < 1.2 GPa has a negligible effect on the Orbach process, but magnetic relaxation > 1 GPa increases Raman relaxation and/or quantum tunnelling of magnetisation.
采用 X 射线衍射、磁强计和理论计算相结合的方法，研究了外压对高性能 dysprosocenium 单分子磁体的影响。有效能垒（）从环境压力下的 1300 cm 降低到 3 GPa 下的 1125 cm。我们的结果表明，压缩<1.2 GPa 对 Orbach 过程几乎没有影响，但磁弛豫>1 GPa 会增加 Raman 弛豫和/或磁化的量子隧道效应。
