The rare earth ferrites exhibit a high electrical resistivity as well as an excessive value of magnetic permeability and low power losses that describes a growing interest for electronic applications at higher frequencies. Extensive studies specified the projections of such materials for constructing magnetic field sensors, microwave, recording and reading devices. In this report, the development of nanostructured particles of rare earth ferrites by Solution Combustion Synthesis (SCS) is described. The method uses exothermic reaction to produce a thermal front that moves through the sample converting components to the desired rare earth ferrite nanoparticles. The yttrium, lanthanum, cerium, samarium and iron nitrates were used as metal precursors and glycine as a fuel. The glycine is completely combusted during the thermal decomposition of the nitrates and generates a temperature front that propagates through the sample. Thermodynamic analysis of the systems predicted a maximum adiabatic temperature in the range of 2200-2800 K with generation of carbon dioxide, nitrogen and water vapor. The substantial gas generation during the reaction helps to produce the synthesized powders friable and loosely agglomerated. Increasing the glycine content increased the reaction temperature during the SCS and consequently the particle size.
