Abstracts

EN

The 100 nm particles of Fe_{2}O_{3} and metallic Fe sedimented jointly with Al_{2}O_{3} powder from their suspension in oleic acid exhibit distinguished mobility which depends on the concentration of aluminum oxide. This observation is interpreted as the result of the interparticle Fe-Fe magnetic interactions which lead to the formation of the rigid network of magnetic metallic iron nanoparticles.
