摘要：

Scaling behaviour of sub-coercive field dynamic ferroelectric hysteresis under the influence of stress was investigated in rhombohedral 0.7PZT-0.3PZN bulk ceramic. The scaling relation of hysteresis area < A > against frequency f, field amplitude E-0 and stress sigma for the minor loops takes the form of < A - A(sigma=0)> proportional to f(-0.35) E-0(3.47)sigma(0.38), which is very similar to that of soft and hard PZT ceramics. However, slightly faster responses to f and E-0 indicate the ease of polarization orientation in this simpler domain structure ceramic as compared with commercial PZT ceramics. This study suggests that the domain structures play a significant role in controlling dynamic hysteresis behaviour of ferroelectric materials.
