Abstract
The internal friction (Q - 1) in multiple-components
ceramics PZT type was measured as a function of temperature from
300 to 600 K. An internal friction peak (P2) appears a few dozen degrees below
Curie temperature (TC). The P2 peak of internal friction is found
to be associated with the viscous-elastic mobility of domain walls. The
internal friction due to the viscous-elastic mobility of domain walls was
calculated and compared with the experimental data.
