Single crystals of CaFeO3 have been synthesized at high pressure of 4.5 GPa with a mixture of KClO4, NaCI and CaCl2 as flux and oxidizing agent. The temperature dependence of the resistivity showed a metal-insurating transition at 295 K, corresponding to the charege disproprotionation. A screw-spin type antiferromagnetic transition was observed at 115 K. These results indicated that the crystals were free from oxygen defect. Energy-dispersive powder X-ray diffraction study with synchrotron radiation at high pressure revealed that a moisture was necessary to crystal growth of CaFeO3.
