Abstract

<abstract abstract-type="graphical" xml:lang="en" id="ppsc201400032-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Monodisperse iron nanoparticles of size range 5</bold>–<bold>19 nm with controlled crystallinity and magnetic properties</bold> are synthesized via thermal decomposition of iron pentacarbonyl in the presence of an appropriate ligand. Crystalline body‐centered cubic iron nanoparticles synthesized in the presence of didodecyldimethylammonium bromide exhibit a high saturation magnetization and room temperature ferromagnetic behavior with a remarkable increased stability in the aqueous phase in comparison to amorphous nanoparticles synthesized in the presence of other ligands. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh2cknq97c" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
