Electronic Transition of Cobalt Monoxide under High-Pressure

Year: 2004

Type: article

Abstract: Pressure and temperature dependence of electrical resistance of cobalt monoxide (CoO) was examined using a diamond anvil cell to 133 GPa and 20–300 K. At room temperature, drastic decrease in the electrical resistance (eight orders of magnitude) was observed in the pressure range of 43 to 63 GPa. Another small decrease in the electrical resistance was also observed at about 90 GPa. These results were consistent with the phase transitions at 43 GPa and 80–90 GPa previously observed by in situ X-ray diffraction experiments. Temperature dependence of the electrical resistance showed metallic behavior at 133 GPa, indicating that the physical properties of the cobalt monoxide was completely altered under extreme pressure of 100 GPa region.
