Abstract
A marked magnetic hardening is observed at room temperature on compositions 35NiFe2 O4 .65Mn3 O4 and 30NiFe2 O4 .70Mn3 O4 in the binary system NiFe2 O4 -Mn3 O4 . 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-Mn2 O3 .
