Abstract

Abstract

The spectra of energy dispersive X-ray diffraction with synchrotron radiation of double perovskite compound Sr2CrWO6 have been studied in situ high pressure pressure up to 34.5 GPa using a diamond anvil cell at room temperature. The experimental results indicate that the sample undergoes a crystal structural change at about 9 GPa. The resistance-pressure and capacitance-pressure relationships in the pressure range of 0~20 GPa show that there is an electronic structural change in Sr2CrWO6 in the pressure range of 2~5 GPa.
- synchrotron radiation,
- double perovskite,
- magnetoresistance material
