Synthesis and Morphology of Face Centered Cubic (FCC) Fe-Pt Nanoparticles
FePt nanoparticles with thermally stable room-temperature ferromagnetism are investigated. The monodisperse nanoparticles are prepared by chemical synthesis and a salt-matrix annealing technique. Structural and magnetic characterizations confirm the phase transition from the disordered face-centered cubic structure. In this paper, 3 nm FePt nanoparticles are first synthesized by superhydride re...

متن کاملMagnetic Properties of FePt Nanoparticles Prepared by a Micellar Method
FePt nanoparticles with average size of 9 nm were synthesized using a diblock polymer micellar method combined with plasma treatment. To prevent from oxidation under ambient conditions, immediately after plasma treatment, the FePt nanoparticle arrays were in situ transferred into the film-growth chamber where they were covered by an SiO2 overlayer. A nearly complete transformation of L10 FePt w...
متن کاملStructural and Magnetic Investigations on FePt Nanoparticles
Magnetic nanoparticles and thin films exhibiting a large magnetic anisotropy energy density (MAE) have attracted enormous attention over the last years due to their potential use in magnetic data storage or sensing applications. FePt alloy nanoparticles and films have a huge MAE in the chemically ordered L10 phase. This ordered phase is typically obtained by annealing the as-prepared chemically...
