High-pressure structural behavior of the double perovskite Sr2CrReO6: an experimental and theoretical study
2009 (English)In: High Pressure Research, ISSN 0895-7959, Vol. 29, no 1, 83-86 p.Article in journal (Refereed) Published
The high-pressure structural behavior of Sr2CrReO6 has been studied experimentally using synchrotron radiation and the diamond anvil cell and theoretically using density functional theory. The experimental zero-pressure bulk modulus is B0=1704GPa and the pressure derivative is B0'=4.71.0. These results compare well with the calculated values 172.6GPa and 5.7. A pseudo-cubic unit cell can describe the crystal structure at low pressure, but the tetragonal structure becomes evident at high pressure.
