Abstract: Micro-Raman scattering was used to characterize spinel CoFe2O4 at high temperature up to 870 K and under an external magnetic field up to 6.0 kOe. It was found that the rapid increase in the linewidth of the Raman modes was related to the inter-site cation migration starting at ∼390 K. A red-shift of the Raman peaks induced by the magnetic ordering was observed upon applying a magnetic field at room temperature. Phase analysis of CoFe2O4 powder was also carried out by means of x-ray diffraction and micro-Raman spectroscopy in this work.
