摘要：

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