Ba(Ti1-xZrx)O3 (x = 0.15 and 0.2) single crystal fibers were grown by the laser heated pedestal growth (LHPG) technique. The XRD results show that the grown crystals are of single phase. Temperature dependence of dielectric permittivity, room temperature hysteresis loops and strain were measured. A broad permittivity peak was observed with the temperature of the dielectric constant maximum Tm ≌ 339 K for x = 0.15, and Tm = 310 K for x = 0.2. The data were in agreement with those of corresponding ceramics, indicating that the compositions of the single crystals were similar to those starting stoichiometry (ceramics). The remnant polarization of 8.5 and 4.0 μC/cm2 was obtained for x = 0.15 and 0.2, respectively. The strain level of ~0.065% and high field d33 of ~ 130 pC/N for x = 0.15 were obtained. |
