2009 (English)In: Journal of Applied Physics, ISSN 0021-8979, E-ISSN 1089-7550, Vol. 106, no 8, 084313/1-084313/7 p.Article in journal (Refereed) Published
Double- and triple-walled TiO2/Fe oxide nanotubes with well defined interfaces have been produced in nanoporous Al2O3 templates using at. layer deposition method. The structural properties of each individual layer are dependent on the deposition temps. The outer layers of TiO2 are polycryst. and consist of a phase mixt. of anatase and rutile, while the inner TiO2 layers grown at lower temp. are amorphous. The Fe oxide layers consist of pure hematite when deposited at 500Â°, while a phase mixt. of hematite and magnetite was obtained at 400Â°. The magnetization measurements reveal that the studied nanotubes exhibit weak ferromagnetic behavior and magnetic anisotropy with an easy axis perpendicular to the tube axis.
