Synthesis of nanosized magnetic NiFe2O4 material by a coprecipitation method
2016
Science and Technology Development Journal
Preserved Fulltext
Nanosized NiFe2O4 spinel material has been synthesized by the coprecipitation method by hydrolysis of Ni(II) and Fe (III) cations in boiling water. The DTA/TGA, XRD, SEM, TEM, VSM results showed that NiFe2O4 crystals formed after calcinating at 700 oC for 2 h exhibited the cubic structure, with the size of 30-50 nM. Mr, Ms and Hc values were 1.06 emu/g, 14.94 emu/g and 61.57 Oe, respectively. The crystal size significantly increased with increasing calcination temperature.
