| 中文摘要 | The high-pressure phase of iridium-based compound Ba3CaIr2O9 was synthesized using high-pressure sintering. Being different from the distorted hexagonal BaTiO3 structure of the ambient Ba3CaIr2O9, the high-pressure phase crystals into the 1:2 B-site-ordered perovskite structure with the space group P-3m1 (Z = 1). Through fitting the X-ray powder diffraction (XRD) data with Rietveld analysis, in which the obtained R-p, R-wp, and R-exp factors are 7.49%, 11.4%, and 4.82%, respectively, the lattice parameters are a = 5.8296(1)angstrom and c = 7.1659(2)angstrom. The atomic coordinates and the main interatomic distances and bond angles were also obtained. The relationship of electrical resistivity versus temperature shows that the high-pressure phase of Ba3CaIr2O9 is a semiconductor in the temperature range of 5-300 K. The measurement of temperature dependence of magnetic susceptibility indicates that it is paramagnetic. (C) 2008 Elsevier Inc. All rights reserved. |
