Development of non toxic magnetic beads has been strongly desired to cure more effectively for patients having diseases such as cancer and osteosarcoma. In this study, Fe doped calcium phosphate powders were prepared by aqueous solution process. The crystal phase of obtained samples had a hydroxyapatite (HAp)-related structure with low crystallinity, and the crystallinity of samples decreased with increasing ratio of Fe (RFe). The crystallinity of samples improved by heat treatment more than 1073 K for 2 hours and α-Fe2O3 phase was generated as a second phase. The lattice parameter of HAp phase drastically changed at RFe=1 mol% caused by the difference of ion radius between Ca ion and Fe ion, and there was a trend of that the a-axis shrinks and c-axis expands by further increment of RFe. The obtained powders had granular crystals with 10 nm in diameter. All samples showed paramagnetic property, and the maximum magnetization was 3×10-2 emu/g at RFe=5 mol%.
