نبذة مختصرة : 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 CaCu3Fe4O12 perovskite 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.
