| Title: | Processing and properties of Yb-doped BiFeO₃ceramics | Authors: | Yan, Z Wang, K Qu, JF Wang, Y Song, ZT Feng, SL |
Issue Date: | 20-Aug-2007 | Source: | Applied physics letters, 20 Aug. 2007, v. 91, no. 8, 082906, p. 1-3 | Abstract: | The authors prepared Yb-doped bismuth iron oxide ceramics (Bi[sub 1−x]Yb[sub x]FeO₃, with 0 ≤ x ≤ 0.20) by rapid liquid phase sintering method and investigated the material’s structures and electrical properties. The x-ray diffraction measurements showed that the doping of Yb has induced noticeable lattice distortion in the ceramics, and a largest distortion was observed when the concentration of Yb was 15%. By doping electrical resistivity, ferroelectric and dielectric properties of the ceramics were improved. Among all samples, BiFeO₃doped with 15% Yb was found to have the smallest leakage current density (<10⁻⁷ A/cm²) and the largest remnant polarization (8.5 μC/cm²). | Keywords: | Bismuth compounds Crystal structure Current density Dielectric hysteresis Dielectric polarisation Doping profiles Electrical resistivity Ferroelectric ceramics Leakage currents Permittivity Rapid thermal processing Sintering X-ray diffraction Ytterbium |
