  • Abstract
    A marked magnetic hardening is observed at room temperature on compositions 35NiFe2O4.65Mn3O4and 30NiFe2O4.70Mn3O4in the binary system NiFe2O4-Mn3O4. From the effects of aging temperature and time upon the magnetic hardening, the measurements of the change of Curie temperature by aging, the results of X-ray and chemical analyses, and microscopic and electron microscopic observations of microstructure, the new findings have been concluded to come from the precipitation of γ-Mn2O3.
