Abstract:
A method of forming a magnetic alloy nanoparticle film, comprising:forming a metal salt solution with a reducing agent and stabilizing ligands;introducing an organometallic compound into said metal salt solution to form a mixture;heating said mixture to a temperature between 260.degree. C. and 300.degree. C.;adding a flocculent to cause said magnetic alloy nanoparticles to produce a precipitate out of said mixture without permanent agglomeration;forming a dispersion with said precipitate;depositing said dispersion on a solid surface;annealing said dispersion in an inert atmosphere at temperature up to 650.degree. C.; andcooling said dispersion under an inert atmosphere.
