Abstract
AbstractThe EQI in polycristalline (Pb0.925Ba0.075)ZrO3 has been investigated in the temperature range 22 to 240 to 22 °C by time differential perturbed angular correlation measurements. For the application of this technique (Pb0.925Ba0.075)ZrO3 was doped with small amounts of radioactive Hf181. According to the crystal structure studies this compound exhibits phase transitions at 175 °C (antiferroelectric → ferroelectric) and at ≈︁205 °C (ferroelectric → paraelectric); it exhibits also a large temperature hysteresis at the lower transition. It is shown that the electric field gradient (EFG) exhibits a sharp discontinuity at approximately 170 °C, corresponding to the first phase transition, and a slightly sharp discontinuity at approximately 200 °C, corresponding to the second phase transition. In the cubic phase a remaining EFG is observed, which is probably caused by lattice imperfections in the source. No any variation of the EFG following the hysteresis loop is found.
