文摘

Fe₃O₄ particles have been synthesized using co-precipitation method employing HCl and NH₄OH as dissolving and precipitating agents, respectively. The particles synthesized without and with polyethylene-glycol (PEG)-400 as template having the particle size <50 nm were dissolved in tetra-methyl-ammonium-hydroxide (TMAH) surfactant to form a magnetic fluid, which was then spin-coated onto the aluminum substrate. The results of coating were characterized for studies covering the particles distribution on the surface, their morphologies, and magnetic properties.
