Abstract

Magnetic nanoparticles have many important applications in the technological, environmental, and medical fields due to their special properties (such as superparamagnetism). The main objective of this research is to obtain a magnetic ferrite. The solgel/combustion method was used to produce nanoparticles of cesium ferrite (CsFeO2). Fourier transform infrared spectroscopy characterized the samples, indicating a ferrite phase at the peaks at 343 and 318 cm-1 and the metal-oxygen bond vibrations of the atoms in tetrahedral and octahedral sites.
