摘要:

The aging of dielectric, elastic and piezoelectric properties is caused by a reduction of the 90° domain wall mobility. Defect dipoles in the domains orient slowly in energetically preferred directions. The oriented defects increase the force constant for the reversible domain wall displacement by electric or elastic fields. Observations of fatigue in bulk materials are briefly discussed.
