Howard, L. E. M. and Nguyen, H. L. and Giblin, S. R. and Tanner, B. K. and Terry, I. and Hughes, A. K. and Evans, J. S. O. (2005) 'A synthetic route to size-controlled fcc and fct FePt nanoparticles.', Journal of the American Chemical Society., 127 (29). pp. 10140-10141.
We report here a new synthetic route to FePt nanoparticles using a stoichiometric mixture of Na2Fe(CO)4 and Pt(acac)2. The structure of FePt nanoparticles, their size, chemical composition, and magnetic property can be controlled by various synthetic parameters, such as the solvent type, nature, and molar ratio of surfactants and stabilizers, synthesis temperature, and purification process. Partially ordered fct (L10) nanoparticles with room temperature magnetic coercivity can be synthesized directly in tetracosane solution at 389 C. The fcc FePt synthesized in nonadecane can be transformed into the magnetically important fct phase at 430 C without significant particle sintering.
