Morphologically Templated Growth of Aligned Spinel CoFe2O4 Nanorods

Uniaxially aligned CoFe2O4 nanorods (see Figure) are obtained by coprecipitation of Co2+, Fe2+, and C2O42– ions in a microemulsion solution, and subsequent high‐temperature decomposition of CoFe2(C2O4)3. Each nanorod is made up of a “tectonic” assembly of CoFe2O4 nanocrystals. Magnetization of such...

Zusammenfassung:Uniaxially aligned CoFe2O4 nanorods (see Figure) are obtained by coprecipitation of Co2+, Fe2+, and C2O42– ions in a microemulsion solution, and subsequent high‐temperature decomposition of CoFe2(C2O4)3. Each nanorod is made up of a “tectonic” assembly of CoFe2O4 nanocrystals. Magnetization of such CoFe2O4 materials may lead to their use in high‐density magnetic recording media and high‐performance electromagnetic and spintronic devices.
