Abstract
Magnetic relaxation measurements were performed in the temperature ran ge 200<T(K)<800 on vacancy-doped polycrystalline magnetite. Important relaxation peaks have been observed in the temperature ranges 250<T(K) <350 (peak III) and 400<T(K)<600 (peak I). Particular attention has be en focused on the behavior of peak I where isothermal measurements hav e extended over times up to 10(5) s. It is argued that the main featur es of peak I are compatible with a dislocation relaxation.
