Domain structure of modified lead titanate ceramics

For modified lead titanate ceramics, the 90 degrees domain rotation after poling was determined by X-ray diffraction analysis. The domain structure of lead titanate ceramics modified with samarium poled at different electric fields was observed. The results show that the percent of 90 degrees domain rotation during the poling was lower, and there were 90 degrees and 180 degrees domains in all the samples poled at a 0-50-kV/cm electric field. There was not ample evidence to prove the full rotation of the 90 degrees domain. However, the domain wall motion seems to be altered by increasing the poling electric field.<
