Title (EN) IRON-BASED NANOPARTICLES AND GRAINS
(FR) NANOPARTICULES ET GRAINS À BASE DE FER
Abstract:
(EN) Example nanoparticles may include an iron-based core, and a shell. The shell may include a non-magnetic, anti-ferromagnetic, or ferrimagnetic material. Example alloy compositions may include an iron-based grain, and a grain boundary. The grain boundary may include a non-magnetic, anti-ferromagnetic, or ferrimagnetic material. Example techniques for forming iron-based core-shell nanoparticles may include depositing a shell on an iron-based core. The depositing may include immersing the iron-based core in a salt composition for a predetermined period of time. The depositing may include milling the iron-based core with a salt composition for a predetermined period of time. Example techniques for treating a composition comprising core-shell nanoparticles may include nitriding the composition.
(FR) Des exemples de nanoparticules peuvent comprendre un noyau à base de fer, et une enveloppe. La coque peut comprendre un matériau non magnétique, anti-ferromagnétique ou ferrimagnétique. Des exemples de compositions d'alliage peuvent comprendre un grain à base de fer, et un joint de grain. Le joint de grain peut comprendre un matériau non magnétique, anti-ferromagnétique ou ferrimagnétique. Des techniques données à titre d'exemple permettant de former des nanoparticules noyau-enveloppe à base de fer peuvent consister à déposer une enveloppe sur un noyau à base de fer. Le dépôt peut consister à immerger le noyau à base de fer dans une composition de sel pendant une durée prédéterminée. Le dépôt peut consister à broyer le noyau à base de fer avec une composition de sel pendant une durée prédéterminée. Des techniques données à titre d'exemple permettant de traiter une composition comprenant des nanoparticules noyau-enveloppe peuvent consister à nitrurer la composition.
