摘　　要：The hybrid particles composed of hydroxyapatite （HAp） and ferrite （ γ-Fe203） were synthesized by two-step precipitation method. The effect of reaction temperature on the morphology of the hybrids was also studied. The resultant hybrids were characterized by transmission electron microscopy （TEM） and X-ray diffraction analysis（XRD）. It was found that γ-Fe203 nanoparticles dispersed within the HAp matrix and these hybrids had a feather-like or spherical morphology when synthesized at 90 ℃ or room temperature, respectively. The magnetic properties of the hybrid showed good superparamagnetic feature, and they could be controlled by the external magnetic field.The hybrid particles composed of hydroxyapatite （HAp） and ferrite （ γ-Fe203） were synthesized by two-step precipitation method.
