Linear temperature scaling of ferroelectric hysteresis in Mn-doped Pb(Mn1/3Sb2/3)O3-Pb(Zr,Ti)O3 ceramic with internal bias field

The temperature scaling of dynamic hysteresis was investigated in Mn-doped Pb(Mn1/3Sb2/3)O-3-Pb(Zr,Ti)O-3 ceramic with internal bias field. A set of simple linear temperature scaling relations were established for hysteresis area < A >, coercivity E-c, and internal bias field E-i, which are different from the power-law scaling relationships for the soft and hard PZT ceramics. The proposed scaling relation between < A > and T can be predicted by the temperature dependent response of E-c and vice versa. It is suggested that the thermal deaging which related to the redistribution of the preferentially oriented defect dipoles is responsible for these dynamic hysteresis behaviors.
