摘要：
Measurements of the magnetic after-effect in magnetite have been made in the temperature range 200 to 600 K. Important relaxation peaks have been observed in the temperature range 250 to 350 K (peak III) and 400 to 550 K (peak I). A study of both the dynamics and the parameters of the defects are consistent with an interpretation of peak III and peak I in magnetite as a combined after-effect due to octahedrally coordinated vacancies.
