Wet-chemical synthesis and magnetic property studies of Fe(III) ion substituted hydroxyapatite

High phase purity Fe(III) substituted hydroxyapatite (HA) was successfully synthesized through wet-chemical processing and characterized for the first time. The M-H magnetization curves of the synthesized, new materials appear to show superparamagnetic behavior for the 10 mol% Fe. These results indicate that the material could be potentially used for a contrasting agent in magnetic resonance imaging and targeted drug delivery.
