Abstract
We report a study of aftereffect processes in magnetite with magnesium subs titutions. The study observed the processes by means of disaccommodation te chniques. We have recorded the time evolution of the initial magnetic susce ptibility after sample demagnetization of polycrystalline specimens with no minal composition MgxFe3-xO4, 0 less than or equal to x less than or equal to 1 in the temperature range from 200 K to 500 K. We find that magnesium s ubstitutions reveal interesting results about magnetic aftereffects in oxid e spinels.
