In this investigation were synthesized the manganese, zinc and rare earth<br />

ferrites presenting spinel-type structure, the stoichiometric ratio for these<br />

ferrites were 0.5:0.5:1.9:0.1. According to literature, these magnetic material are<br />

under investigation for biomedical proposes, solution combustion method is an<br />

easy technique to obtain ferrites, the synthesis of some these compounds have<br />

already been obtained by other methods reported in the literature, however,<br />

the combustion method using of urea was not reported.<br />

The methodology was proposed to obtain nanoparticles whit a high crystallinity<br />

and purity, nevertheless is important to obtain these nanoparticles with a low<br />

size distribution and controllable size, the solution combustion method offers<br />

many advantages to cover these necessities.<br />

In this work were synthesized Mn0.5Zn0.5Fe1.9 RE0.1O4 samples, where RE=Nd, Pr,<br />

La and Sm. Those were obtained using urea as a fuel, the characterization<br />

realized consisted in the structural study by XRD technique, the morphology of<br />

the samples was studied by field emission scattering electron microscopy, these<br />

samples were also characterized by infrared spectroscopy and<br />

thermogravimetric assay in order to obtain more information about the purity<br />

of the samples.<br />
