“…Physical, chemical and structural properties of oxide powders depend on preparation method and thermal treatment applied during preparation. A wide variety of methods are being used to synthesize spinel ferrite nanoparticles including citric acid combustion [12], sol-gel auto combustion [13], hydrothermal [14], co-precipitation methods [15,16]. In addition, thermolysis [17], wet chemical co-precipitation technique [18], self-propagating and microemulsion [19,20], are also used.…”

Mg ferrite was successfully synthesized by adopting a simple co-precipitation route. A physical property of Mg ferrite has been investigated employing XRD, FTIR, SEM, EDS, AFM and Raman spectroscopic techniques. The XRD results indicated the formation of single phase spinel ferrite with crystalline size of 36 nm. FTIR results confrmed ferrite tetrahedral (580 cm −1) and octahedral sites (430 cm −1) metal oxygen vibrations. The Raman result revealed the well defined Raman active modes of synthesized sample. Scanning electron microscopic (SEM) studies revealed nano crystalline nature of the sample. An elemental composition of the sample was studied by energy dispersive spectroscopy (EDS). Crystallite size, X-ray density, hopping length, and magnetic properties of the product are also reported. AFM provides surface roughness. The magnetic hysteresis curves clearly indicate the soft nature of the prepared nanoferrite. The Raman spectra shows five Raman active modes (A 1g + E g + 3F 2g) which are expected in the spinel structure and Raman spectra has a very good agreement with reported data. Various magnetic parameters such as saturation magnetization (M s), and remanence (M r) and coerciviy (H c) are obtained from the hysteresis loops.
