The composition in starting solution was optimized, and the resulting NiFe2O4 was formed at temperature of around 550–600 °C, which is much lower than that observed from the solid-state reaction. Magnetic investigation indicates that samples are soft magnetic materials with low coercivity and with the saturation magnetization close to the bulk value of Ni ferrite.enghttps://creativecommons.org/licenses/by/4.0/Physical Sciences and MathematicsUltrafine NiFe2O4 powder fabricated from reverse microemulsion processjournal contribution10.1063/1.1555394
