Abstract
A magnetic composition comprised of cobalt ferrite nanoparticles dispersed in an ionic exchange resin.
Claims3
A magnetic composition comprised of cobalt ferrite nanoparticles dispersed in an ionic exchange resin, wherein the cobalt ferrite nanoparticles are of the formula CoFe2O4, wherein the composition has a magnetic anisotropy constant of about 107 erg/cm3 at about 300 K and further comprising a dopant selected from the group consisting of Group I, Group II, Group IIIa/b, rare earth elements, transition metals oxides thereof and mixtures thereof.
A magnetic composition comprised of substantially monodispersed cobalt ferrite nanoparticles in an ionic exchange resin, wherein the cobalt ferrite nanoparticles are of the formula CoFe2O4, wherein the composition has a magnetic anisotropy constant of about 107 erg/cm3 at about 300 K and further comprising a dopant selected from the group consisting of Group I, Group II, Group IIIa/b, rare earth elements, transition metals oxides thereof and mixtures thereof.
