Abstract
We report the structural and magnetic properties of as-deposited and thermally annealed FePt/C granular multilayer films. The as-deposited system exhibits a disordered fcc FePt phase with an average grain size of 3 nm. Thermal annealing at 650 °C results in partial L10L10 ordering and an associated grain growth to 7 nm. Mössbauer measurements show that there is no non-magnetic component present, suggesting that carbon resides only in the grain boundary region. The ferromagnetic grains are magnetically decoupled.
► FePt/C granular films prepared by Ion beam sputtering. ► FePt nanoparticles. ► Evolution of superlattice peaks by thermal annealing. ► Formation of magnetically decoupled phases.
