Magnetic composite (MC) particles consisting of finding hydroxyapatite and iron oxides (HAp/FeOxid), synthesized at both pyrolysis temperatures during MC synthesis, i.e., 800, 900, and 1000°C and at the various ferroxide concentrations in the HАp : FeOxid composite, i.e., 1 : 3, 1 : 2, and 1 : 1 (at a pyrolysis temperature of 1000°C). It is found that the HAp/FeOxid MCs are formed by the hydroxyapatite matrix providing biological compatibility of the MC containing iron oxide particles. Mössbauer studies show that maghemite (γ-Fe_2O_3), magnetite (Fe_3O_4), ε-Fe_2O_3, and akaganeite (β-FeOOH) phases are simultaneously observed in synthesized HAp/FeOxid MCs. The content of ε-Fe_2O_3 component having giant magnetic anisotropy is to ~40% of iron oxides (FeOxid) in HAp/FeOxid MCs, which makes obtained MCs very promising for various applications, including biomedical ones.
