Effects of Cu addition on the structure and magnetic properties of L10-FePt nanoparticles prepared by sol–gel method
Source abstract
Abstract
(FePt)100Cu0, (FePt)95Cu5 and (FePt)90Cu10 nanoparticles (NPs) were successfully synthesized by the sol–gel method. The relationship between Cu doping and structure and magnetic properties of L10-FePt NPs was studied. The results indicated that all three samples originated a L10-FePt structure and Cu doping did not destroy the ordered structure of L10-FePt. By increasing the Cu content, c/a ratio of the FePtCu NPs linearly decreased. Pawley refinement showed symmetry of (FePt)95Cu5 NPs was still tetragonal. When the Cu concentration increased from 0 to 10 %, coercivity increased from 7,050 to 11,250 Oe. This result confirms that the prepared alloys can be promising candidates for magnetic storage applications.
