Scaling behavior of subcoercive field dynamic ferroelectric hysteresis under influence of stress was investigated in Pb(Zn(1/3)Nb(2/3))O(3)-modified Pb(Zr(1/2)Ti(1/2))O(3) (PZT) bulk ceramic. The scaling relation of hysteresis area < A > against frequency f, field amplitude E(0), and stress sigma for the minor loops takes a form of < A-A(sigma=0)>proportional to f(-0.42)E(0)(3.65)sigma(0.24), 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 to commercial PZT ceramics.
