Abstract
In this work we study the remanent magnetization in various spin glass models after the removing of a strong magnetic field.
We compare the behavior of the remanent magnetization of infinite-range models and of more realistic short-range models. In
both cases we find a reasonable agreement with a simple phenomenological law at low temperatures, especially in the case of
continuously distributed exchange interactions. The relaxation of the internal energy shows a more complex behavior.
