The effect of barium (Ba) and strontium (Sr) additions on the electrical properties of lead lanthanum zirconate stannate titanate (PLZST) ceramics and their electrically induced phase change behavior was examined. Sr additions decreased both the ferroelectric (FE) ↔ antiferroelectric (AFE) transition temperature ( T AFE‐FE ) and the temperature of the maximum dielectric constant ( T MAX ). This indicates that Sr additions stabilize the AFE phase. Along with B‐site modifications Sr additions can be used to decrease the switching field and hysteresis. Ba additions caused the temperature range of the AFE phase to narrow by increasing T AFE‐FE and decreasing T MAX . This behavior indicates an ability to lower the switching field and suppress hysteresis. Using a combination of both A‐site and B‐site modifications it is possible to tailor the properties (for example, switching field, hysteresis, and operating temperature range) of this group of phase change materials to meet the requirements of specific applications.
