We report the synthesis of single-phase Fe-doped hydroxyapatite (HAp) [Ca10-x Fe (x) (PO4)(6)(OH)(2) (0.0 ae x ae 0.3)] and enhanced dielectric constant of HAp with Fe doping. Rietveld analysis shows the change in x-axis-oriented lattice constant a in Fe-doped x = 0.1 and 0.3 compositions in comparison with parent HAp, while z-axis-oriented lattice constant c does not show any considerable change. Analysis of absorbance data shows two new symmetric stretching peaks for Fe-doped x = 0.1 and x = 0.3 compositions, which are not present in parent HAp. Magnetic measurements show paramagnetic behaviour of all Fe-doped samples at 300 K. Fe-doped Ca9.9Fe0.1(PO4)(6)(OH)(2) composition shows increase in impedance in the presence of 500 Oersted (Oe) applied magnetic field in comparison with impedance in the absence of magnetic field. Ca9.9Fe0.1(PO4)(6)(OH)(2) composition shows increase in dielectric constant in comparison with parent HAp in frequency range 5-35 MHz. Fe-doped Ca9.9Fe0.1(PO4)(6)(OH)(2) composition shows similar to 970% colossal magnetoimpedance at 100 Hz and similar to 200% at 20 MHz frequency.
