Abstract

The unipolar fatigue behavior of undoped Li0.06Na0.52K0.42NbO3 (LNKN6-a) and the same compound with additives (LNKN6-b) were observed. Unipolar cycling was performed between room temperature and 150 degrees C under a high unipolar electric field of 4kV/mm. LNKN6-a fatigued under crack formation throughout the examined temperature range. The switchable polarization 2P(r) of LNKN6-a decreased for 20% (=2 mu C/cm(2)) at 150 degrees C. In contrast, mechanical degradation was not observed in LNKN6-b. The switchable polarization 2P(r) of LNKN6-b decreased for 15% (=3.2 mu C/cm(2)) at 150 degrees C. It should be noted that at 50 degrees C, fatigue-free behavior was observed for LNKN6-b over at least 106 cycles. The influence of phase transition on this fatigue-free behavior was discussed.
