Abstract

We demonstrate an advanced chemical vapour deposition (CVD) approach in which the addition of Pt-containing hydrocarbons to ferrocene allows the nucleation of a novel carbon-foam material completely filled with elemental Fe and Pt crystal-phases. These phases are then found to alloy into tetragonal FePt and cubic FePt₃ in specific annealing conditions. A dependence of the FePt nucleation on the Ar/H₂ flow rate is reported. In addition, high pressure (5 GPa) experiments are found to favor the formation of a single FePt₃ encapsulated phase together with the nucleation of C-O rich carbon layers in the foam surface.
