In this study, the AFE-FE switching of lead lanthanum stannate zirconate titanate (PLSnZT) was investigated and efforts were made to find high strain compositions with low switching field and hysteresis. Compositional modifications on both the A- and B- site were attempted in order to modify material properties. The B-site modifications were completed through manipulation of the Ti:Sn and Zr:Sn ratios. On the other hand, the A-site modifications were accomplished by the addition of Ba and Sr. It was demonstrated that one can tailor material properties to fit specific application requirements through compositional modifications.","PeriodicalId":14772,"journal":{"name":"ISAF '96.

The amount of the oxide additive in the BSTO matrix was varied from 1 wt% to 60 wt%. The thin films were deposited on single crystal sapphire substrates. The intent of this work is to study the effect of the oxide additive on the crystal structure of BSTO and compare it to its bulk ceramic counterpart. Glancing angle X-ray diffraction (GAXRD), Fourier transform Raman spectroscopy (FT-Raman), and Fourier transform Infrared spectroscopy (FT-IR) were utilized in this work. Since the bulk ceramics of these composites of BSTO have already been implemented in low loss electronic scanning antennas, it is necessary to characterize the material in its thin film form for applications at higher microwave frequencies (>35 GHz).","PeriodicalId":14772,"journal":{"name":"ISAF '96.

Additions of MnO/sub 2/ to PZT can result in materials with zero temperature coefficients and low propagation losses. The available Q/sub m/'s of PZT materials however, can limit their usefulness in energy-critical applications. In this work, a novel approach to improving the performance of PZT was attempted. The effect of both a dopant atom (Mn) and electron dopant pyrochlore phase, Sr/sub 2/Sb/sub 2/O/sub 7/, were examined. MnO/sub 2/ was added at 0.1, 0.3, and 0.5 wt% levels while the pyrochlore was added at the 5 mol% level. It was postulated that the pyrochlore phase might limit grain growth and reduce domain motion, thus increasing Q/sub m/. It was further postulated that compositions with both the pyrochlore and Mn doping should yield even greater Q/sub m/ values. Properties of interest, k/sub p/, Q/sub m/, e, and loss, were measured by the resonance method. In summary, Mn doping was effective in improving properties. Pyrochlore additions did reduce grain size; however, the properties were degraded.","PeriodicalId":14772,"journal":{"name":"ISAF '96.

Bright-field imaging has revealed a common sequence of domain-like states with increasing x. Normal micron-sized ferroelectric domains were found for x>0.40. Tweed-like structures were found for x/spl sim/0.35. These tweedlike structures are similar to those previously reported in pre-martensitic states. Paraelectric clusters were found for x<0.30. The paraelectric cluster state was characterized by the lack of self-assembly amongst embryos and the presence of relaxor behavior in the macroscopic response characteristics.
