Stress dependence and scaling behavior of subcoercive field dynamic ferroelectric hysteresis were investigated in rhombohedral 0.5Pb (Zr1/2 Ti1/2) O3 -0.5Pb (Zn1/3 Nb2/3) O3 (0.5PZT-0.5PZN) bulk ceramic with profound relaxor characteristics. The scaling relation of hysteresis area 〈A〉 against frequency f, field amplitude E0, and stress for the minor loops takes a form of 〈 A- A=0 〉 f-0.34 E0 3.68 0.35, which is very similar to that of soft and hard lead zirconate titanate ceramics with the same disrupted domains. This study suggests that the domain structures play a significant role in controlling the dynamic hysteresis behavior of ferroelectric materials. © 2008 American Institute of Physics.
