PURPOSE : A core-shell structured nanoparticle having hard-soft magnetic heterostructure, a magnet manufactured by using the nano particle and a manufacturing method thereof are provided to overcome restriction of physical, magnetic characteristics of the conventional ferrite single-phase material as having advantage of low price and being free from supply and demand problem of the rare earth resource.CONSTITUTION : According to a method for manufacturing a core-shell structured nanoparticle having hard-soft magnetic heterostructure, a solution in slurry state including more than one kind selected from a group comprising chelate metal complex, metal salt, metal compound and metal nano powder and ferrite nano powder is acquired. The solvent of the solution is evaporated and is converted into gel state of viscosity property. The gel is heated to form nano particles.COPYRIGHT KIPO 2013
