A new piston-cylinder pressure cell for electron spin resonance (ESR) has been developed. The pressure cell consists of a double-layer hybrid-type cylinder with internal components made of the ZrO2-based ceramics. It can generate a pressure of 2 GPa repeatedly and reaches a maximum pressure of around 2.5 GPa. A high-pressure ESR system using a cryogen-free superconducting magnet up 10T has also been developed for this hybrid-type pressure cell. The frequency region is from 50 GHz to 400 GHz. This is the first time a pressure above 2 GPa has been achieved in multi-frequency ESR system using a piston-cylinder pressure cell. We demonstrate its potential by showing the results of the high-pressure ESR of the S=1 system with the single ion anisotropy NiSnCl6·6H2O and the S=1/2 quantum spin system CsCuCl3. We performed ESR measurements of these systems above 2 GPa successfully.
一种用于电子自旋共振（ESR）的新型活塞 - 圆筒压力室已被开发出来。该压力室由一个双层混合式圆筒组成，其内部部件由基于ZrO₂的陶瓷制成。它能够反复产生2 GPa的压力，并且最大压力可达约2.5 GPa。还为这种混合式压力室开发了一种使用高达10T的无液氦超导磁体的高压ESR系统。频率范围为50 GHz至400 GHz。这是首次在使用活塞 - 圆筒压力室的多频ESR系统中实现2 GPa以上的压力。我们通过展示具有单离子各向异性的S = 1系统NiSnCl₆·6H₂O和S = 1/2量子自旋系统CsCuCl₃的高压ESR结果来证明其潜力。我们成功地对这些系统在2 GPa以上进行了ESR测量。
