Abstract
The present invention provides a method for preparing iron oxide magnetic particles and iron oxide magnetic particles prepared thereby, wherein the method includes (a) synthesizing a complex by reacting iron and one or more compounds selected from the group consisting of an aliphatic hydrocarbonate having 4 to 25 carbon atoms and an amine compound, (b) synthesizing an iron oxide crystal nucleus by mixing the complex with a mixture of an unsaturated aliphatic hydrocarbon-based compound having 4 to 25 carbon atoms and an ether-based compound, and (c) forming a shell by mixing the iron oxide crystal nucleus and an MXn compound with a mixture of an unsaturated aliphatic hydrocarbon-based compound having 4 to 25 carbon atoms and an ether-based compound, wherein M is a heavy atom element, X is a halogen element, and n is an integer of 1 to 6.
