Lithium Ferrites Prepared Differently and its Magnetic Properties

The purpose of this chapter is to compare the structural, morphologic and magnetic properties of lithium ferrite nanoparticles obtained by solid state reaction (SSR) and sol-gel (SG) methods using nitrates as raw materials. Samples structure was studied by X-ray diffraction and Raman spectroscopy and their morphology by scanning electron microscopy. SG method favored the appearance of the single lithium ferrite crystal phase at lower heat treatment temperature. The more suitable samples to be applied in electronic devices are the ones treated at 1200 ºC, which present the highest levels of saturation magnetization (≈68 emu/g at 300 K).
