	abstract = {XRD and FT-IR were used to characterize hydroxyapatite (HA) films, which were prepared using rf sputtering. The morphology of the sample films was analyzed using SEM. From the FT-IR spectrum, sputtered HA films showed structural changes, namely the decrease of the strength of the liberational mode of OH group, indicating the presence of a poorly crystalline phase. XRD results of films obtained at 500 W and 400 W showed that the crystallinity of the 500 W 4h e 2h samples was low, just showing a very incipient degree of crystalline structural structural arrangement, while in the 400 W-4h and 2h samples there was no crystalline structure, with only a slight diffraction of the 002 and 301 HA planes.},
