摘要：
NiFe2O4 nano-particles were synthesized by a simple and cost-effective method using Ni and Fe nitrates and glycine. Significant effect of the ratio between glycine and nitrates on the physical parameters like crystalline phase, crystallite size, and particle size, lattice constant and magnetic properties of the nano-particles has been investigated. The X-ray diffraction, IR and selected-area electron diffraction results indicated that the synthesized nickel ferrite particles have the nanometer size and inverse spinel structure. Room temperature magnetization results showed a ferromagnetic behavior of the NiFe2O4 nano-particles, with saturation specific magnetization values in the range of 2.387-57 emu/g at 15 kOe. The corecivity of the NiFe2O4 nano-powders changed from 65.58 to 148.8 Oe according to the change in the ratio between glycine and nitrates. (C) 2009 Elsevier B.V. All rights reserved.
