摘要：

The aging behavior of the ac susceptibility of randomly substituted K1-xLixTaO3 crystals reveals marked differences with spin glasses in that cooling rate effects are very important. The response to temperature steps (including temperature cycles) was carefully studied. A model based on thermally activated domain growth accounts for all the experimental results, provided one allows for a large distribution of pinning energies, in such a way that "slow" and "fast" domains coexist. Interesting similarities with deeply supercooled liquids are underlined. [S0031-9007(98)07804-1].
