Stress dependence and scaling of subcoercive field dynamic hysteresis in 0.5Pb(Zr{sub 1/2}Ti{sub 1/2})O{sub 3}-0.5Pb(Zn{sub 1/3}Nb{sub 2/3})O{sub 3} ceramic

Stress dependence and scaling behavior of subcoercive field dynamic ferroelectric hysteresis were investigated in rhombohedral 0.5Pb(Zr{sub 1/2}Ti{sub 1/2})O{sub 3}-0.5Pb(Zn{sub 1/3}Nb{sub 2/3})O{sub 3} (0.5PZT-0.5PZN) bulk ceramic with profound relaxor characteristics. The scaling relation of hysteresis area <A> against frequency f, field amplitude E{sub 0}, and stress {sigma} for the minor loops takes a form of <A-A{sub {sigma}}{sub =0}>{proportional_to}f{sup -0.34}E{sub 0}{sup 3.68}{sigma}{sup 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.
