The elastic strain associated with the field-induced transition from an anti ferroelectric phase to a ferroelectric one has been measured at several temperatures in a PZT-family ceramic Pbo.ggNbo.02[(Zr0.6Sno.s)o.94Ti0.06 lo.9803. Reproducible large strain change of about ARIR 0.l % due to the forced transition may be promising for digital microdisplacement transducers. So-called “inverse hysteresis” in the strain curve is observed in a temperature range between -70°C and 10°C, whichis also useful as a shape memory device for mechanical clamping and similar applications.
