L1 structure formation in slow-cooled Fe-Au nanoclusters

P Mukherjee, Y Zhang, MJ Kramer, LH Lewis… - Applied Physics …, 2012 - pubs.aip.org
An ordered L1 0 structure has been formed in near-stoichiometric Fe-Au alloy nanoparticles.
The L1 0 structure with a= 0.367 nm and c= 0.360 nm was observed in nanoclusters with
diameters below 10 nm after slow cooling from 600 C. The stable L1 0 structure formed from
a parent fcc solid solution phase observed in the as-formed clusters. The fcc phase has a
lattice parameter of 0.417 nm, significantly expanded compared to both Au and γ-Fe. The
saturation magnetization and coercivity of both fcc and L1 0 structures were much lower than …
