The gel was aged for 2 h at room temperature and then dried at 95 C for 72 h. Subsequently, the dried gel was heat treated at 400, 500 or 600 C in air for 30, 60, 90 or120 min. The obtained products were milled and then washed several times with ethanol, in order to remove the ethylene glycol excess. Finally, the powders were dried at room temperature. For the thermal decomposition method, stoichiometric amounts of the acetylacetonates of Fe, Mg and Mn, phenyl ether and oleic acid were placed in a threenecked flask of 250 mL. Subsequently, a thermometer was placed in one of the side necks and a reflux system was adapted. The solution was heated up to 250 C and it was maintained at this temperature for 30, 60 or 90 min. Once the reaction time passed, a precipitate was obtained, which was washed repeatedly with ethanol. Finally, the precipitate was dried at room temperature and milled.
