The temperature scaling of the dynamic hysteresis was investigated in soft ferroelectric bulk ceramic. The power-law temperature scaling relations were obtained for hystersis area < A > and remnant polarization P-r, while the coercivity E-C was found to scale linearly with temperature T. The three temperature scaling relations were also field dependent. At fixed field amplitude E-0, the scaling relations take the forms of < A >proportional to T-1.1024, P-r proportional to T-1.2322, and (E-C0-E-C)proportional to T. Furthermore, the product of P-r and E-C also provides the same scaling law on the T dependence in comparison with < A >. (c) 2007 American Institute of Physics.
