摘要：

The effects of frequency f, field amplitude E-0, and mechanical stress sigma on the hysteresis area < A > and their scaling relations were investigated on soft PZT bulk ceramics. The hysteresis area was found to depend on the frequency and field amplitude with a same set of exponents to the power-law scaling for both with and without stresses, indicating the universality. The inclusion of stresses into the power law was also obtained in the form of < A-A(sigma=0)>proportional to f(-0.25)E(0)sigma(0.44), which indicates the difference of the energy dissipation between the under stress and stress-free conditions and reveals how the hysteresis area decays with increasing stresses.
