Abstract

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.
