Abstract
The iron doped brushite (Fe-DCPD) nano particles were synthesized via co-precipitation method with Fe concentrations (0 <= x <= 1) in steps 0.2. The influence of iron concentration on the crystallinity, particle shape, morphology, optical, magnetic and electrical properties was investigated. The results showed that iron doping content is the crucial factor in the variation of physical properties. The particle shape changed from spheres at x = 0.2 to be fiber network at x = 0.8. The saturation magnetization (M-s) increased from 0.4 (emu/g) at x = 0.2 to 1.6 (emu/g) at x = 0.8 which is considered more than four times with a considerable decrease of coercive field.
