| 中文摘要 | 5d Solid-state oxides K0.84OsO3 (Os5.16+; 5d (2.84)) and Bi2.93Os3O11 (Os4.40+; 5d (3.60)) were synthesized under high-pressure and high-temperature conditions (6 GPa and 1500-1700 degrees C). Their crystal structures were determined by synchrotron x-ray diffraction and their 5d electronic properties and tunnel-like structure motifs were investigated. A KSbO3-type structure with a space group of Im-3 and Pn-3 was determined for K0.84OsO3 and Bi2.93Os3O11, respectively. The magnetic and electronic transport properties of the polycrystalline compounds were compared with those obtained theoretically. It was revealed that the 5d tunnel-like structures are paramagnetic with metallic charge conduction at temperatures above 2 K. This was similar to what was observed for structurally relevant 5d oxides, including Bi3Re3O11 (Re4.33+; 5d (2.66)) and Ba2Ir3O9 (Ir4.66+; 5d (4.33)). The absence of long-range magnetic order seems to be common among 5d KSbO3-like oxides, regardless of the number of 5d electrons (between 2.6 and 4.3 per 5d atom). |
