Abstract

See full text

The present invention relates to hydroxyapatite doped with Fe2+ ions and Fe3+ ions which partially substitute the calcium ions in the crystal lattice. The hydroxyapatite is characterized by an intrinsic magnetism of 0.05 to 8 emu/g, measured by applying a magnetic field of 34 Oe, due to the presence of magnetic nano-domains in the crystal lattice of HA, given the limited amount of magnetic secondary phases present, less than about 3% by volume.
