冷中性子TOF回折計WISHにおけるHybrid-Anvil-Cellを用いた高圧力下中性子回折実験：マルチフェロイクスへの応用

抄録

Recently, we have developed the experimental setup for high pressure neutron diffraction experiment with using Hybrid-Anvil-Cell in combination with high flux cold neutron time of flight (TOF) diffractometer WISH at ISIS. By using this unique setup, we have succeeded in measuring pressure induced magnetic Bragg reflections for the multiferroic compounds CuFeO₂ and TbMnO₃. The former shows pressure induced polar magnetic phases up to 7.9 GPa. For the latter compound, we have determined the magnetic structures under not only high pressure (5 GPa) but also high magnetic field (8 T) condition. In this article, I would like to show utilization of the combination, and encourage researchers in other fields as well as multiferroics to use the unique combination.
