在本研究中，使用小型立方砧装置（W45×D52×H92 cm3，负载能力为1.80 MN）和多砧6-6系统进行了高达10 GPa的高压合成。其性能通过在 10 GPa 和 1400 K 的压力-温度条件下合成铁磁钙钛矿氧化物 CaCu3Fe4O12 来证明。合成的 CaCu3Fe4O12 钙钛矿直径约为 1 mm，高度约为 2 mm，其尺寸足够大，可以使用超导量子干涉装置磁力计在 5-300 K 下进行磁化率测量并通过 X 射线进行相位识别衍射。本研究开发的实验系统在高压合成实验中具有许多优点，小型立方砧装置的技术发展将极大地促进新材料高压合成的进步。
In the present study, high pressure synthesis up to 10 GPa was done using a small cubic anvil apparatus (W45×D52×H92 cm3, load capacity of 1.80 MN) with a multi-anvil 6-6 system. Its performance was demonstrated by synthesizing a ferromagnetic perovskite oxide, CaCu3Fe4O12, at pressure–temperature conditions of 10 GPa and 1400 K. The synthesized CaCu3Fe4O12perovskite was ∼1 mm in diameter and ∼2 mm in height and its size was large enough for performing magnetic susceptibility measurements at 5–300 K using a superconducting quantum interference device magnetometer and phase identification by X-ray diffraction. The experimental system developed in the present study has many advantages when used in high pressure synthesis experiments, and the technical development of a small cubic anvil apparatus will greatly contribute to the advancement of high pressure synthesis of novel materials.
