Abstract
In three relaxer ferroelectrics strong low-field aging effects are found fo r the dielectric susceptibility. Different regimes, marked by different tim e dependence and by different stability under subsequent thermal cycles and field changes, are found in different materials and at different temperatu res. One regime strongly resembles aging in spin glasses, but others do not .
