Title (EN) CORE-SHELL STRUCTURED NANOPARTICLE HAVING HARD-SOFT MAGNETIC HETEROSTRUCTURE, MAGNET PREPARED WITH SAID NANOPARTICLE, AND PREPARING METHOD THEREOF
(FR) NANOPARTICULE À STRUCTURE NOYAU-COQUE PRÉSENTANT UNE HÉTÉRO-STRUCTURE MAGNÉTIQUE DURE-MOLLE, AIMANT PRÉPARÉ AVEC LADITE NANOPARTICULE ET PROCÉDÉ POUR SA PRÉPARATION
Abstract:
(EN) The present invention relates to a core-shell structured nanoparticle having hard-soft heterostructure, magnet prepared from the nanoparticle, and preparing method thereof. The core-shell structured nanoparticle having hard-soft magnetic heterostructure of present invention has some merits such as independence from resource supply problem of rare earth elements and low price and can overcome physical and magnetic limitations possessed by the conventional ferrite mono-phased material.
(FR) La présente invention concerne une nanoparticule à structure noyau-coque présentant une hétéro-structure dure-molle, un aimant préparé à partir de la nanoparticule et un procédé pour sa préparation. La nanoparticule à structure noyau-coque présentant une hétéro-structure magnétique dure-molle selon la présente invention présente des avantages tels que l'indépendance par rapport au problème d'approvisionnement en ressources d'éléments de terres rares et un prix modique, et peut surmonter les limites physiques et magnétiques présentées par le matériau conventionnel en ferrite monophasique.
