Formation of Monodisperse FePt Alloy Nanocrystals Using Air-Stable Precursors: Fatty Acids as Alloying Mediator and Reductant for Fe3+ Precursors

“…Conversely, metallic ones are magnetically strong but typically unstable. Metal alloys, such as FePt and CoPt ones, are reasonably good on both magnetic strength and stability. − For instance, in comparison to the coercivity of the corresponding magnetic oxides, Fe 3 O 4 and γ-Fe 2 O 3 , FePt possesses significantly higher values, either approximately 2 orders of magnitude higher in fct structure or 1 order of magnitude higher in fcc structure. ,, In terms of stability, FePt nanocrystals are found to be even more stable than iron oxides. Alloy nanocrystals are not only interesting in the field of magnetic nanomaterials but also of importance in catalysis, bandgap tuning in semiconductor nanocrystals, etc. − Therefore, fundamental investigations on alloying in the nanometer size regime are of general importance in materials chemistry.…”

Consolidation of FePd nanoparticles by spark plasma sintering

“…As far as consolidation of nanopowders is concerned, spark plasma sintering (SPS) technique has emerged out in recent times e the most efficient route for ceramics, metals, alloys and composites, with a capability of achieving fast densification and minimal grain growth in a short sintering time. Further, the technological realization of the SPS technique in the consolidation of nanopowders of L1 0 -intermetallics such as TiAl [9,10], FeAl [11] and FePt [12,13] has been successfully demonstrated by several researchers. In this context, herein we exploit the potential merits of SPS process for the consolidation of L1 0 -ordered FePd alloys using the constituent nanoparticles processed by the polyol process.…”

Hard magnetic FePt thin films and nanopatterns

“…Recently the ferromagnetic material L1 0 FePt has gained significant attraction [1][2][3][4][5] as a candidate for ultra high density magnetic recording due to its very high anisotropy constant (K 1 ¼ 6:6 Â 10 6 J=m 3 [6,7]) and its high corrosion resistance [8].…”
