Effect of FeCl2 concentration on the properties of magnetic nanoparticles by using Massart's procedure

The effect of variation of FeCl2 concentration on the properties of magnetic nanoparticles produced by Massart's procedure was investigated. Samples with different FeCl2 concentration of 0.1, 0.8, 1.0, 1.2 and 1.5 M were produced. In this technique, an aqueous mixture of ferrous and ferric chlo...
