title: Synthesis and magnetic property of iron ions-doped hydroxyapatite.
abstract: Magnetic Hydroxyapatite (HAP) particles were successfully synthesized at different concentration of Fe2+ by a co-precipitation method. The influences of concentration of doped ions and calcination temperature on the morphology and magnetic property were studied. The iron ions-doped HAP still kept its structure similar to conventional HAP and no second phases were detected. Results indicated that the doping of iron ions decreased the crystallinity and inhibited the c-axis growth and promoted the a-axis growth. HAP particles incorporated with 10% and 50% iron ions exhibited superparamagnetic and with 30% iron ions exhibited weak ferromagnetic characters. In addition, calcination temperature also increased the remnant.
