Structure-property relationships in strontium barium niobate relaxor ferroelectrics

Studies of the structure-property relationships in strontium barium niobate Sr$\sb{\rm x}\rm Ba\sb{1-x}Nb\sb2O\sb6$ (SBN x/1 $-$ x) have been performed using a combination of dielectric spectroscopy, Sawyer-Tower polarization techniques, and transmission electron microscopy (TEM). The dielectric response was found to be strongly dependent on crystallographic orientation, in distinct comparison to the nearly orientation independent response found for Pb-based perovskite relaxors. The dielectric absorption of SBN was also found to be much stronger along the c-axis than along any other orientation. Investigations of the temperature dependence of the high-field polarization behavior found that a square-to-slim loop hysteresis transition occurred rapidly with increasing temperature.
