“…These properties allow a wide range of applications such as in magnetic resonance imaging contrast agents for biotechnology [1,2], gas sensors [3,4], microwave devices [5], carries for targeted drug delivery [6,7] and magnetic nanofluid for hyperthermia cancer treatments [8e10]. There are several routes for preparations of ferrites that include: mechanochemical [11], solegel processing [12e14], co-precipitation [15,16], combustion [17,18], hydrothermal [19], reverse micelle [20] and other methods.…”
