- 論文の詳細を見る
Ferroelectric strontium barium niobate (SBN) single crystal fibers are fabricated from congruent Sr0.61Ba0.39Nb2O6 ceramics by the laser heated pedestal method. For these crystals, the phase components are detected by X-ray diffraction (XRD) analysis and dielectric properties are measured and compared. No other solid solutions during crystal growth are detected by XRD analysis. Two relaxations are observed by dielectric spectroscopy in a distinct temperature range and the relaxation mechanisms are investigated to explain the difference in dielectric behavior. The poling effect on the relaxation is also discussed.
