摘要：

The internal friction and shear modulus for the particulate magnetoelectric composite (x)PbZr0.53Ti0.47O3-(1-x) Mn0.4Zn0.6Fe2O4 have been studied over a temperature range from room temperature to 670K. In the vicinity of the ferroelectric phase transition temperature, we have observed the internal friction peak that is explained in terms of the fluctuation model. The residual internal friction near the ferroelectric Curie point has also been revealed. The residual internal friction is assumed to be due to the interaction of domain boundaries in PbZr0.53Ti0.47O3 with point defects.
