Assembly of high-anisotropy L10 FePt nanocomposite films

“…It is well known that template-mediated synthesis represents an elegant and effi cient approach for producing nanostructured materials [22,23]. Porous alumina templates have many advantages over others [24]; for example, they are resistant to the attack of most organic and in- organic compounds and stable at high temperature. Also, these templates can be easily removed in sodium hydroxide aqueous solution, and the pore size, separation and distribution can be tuned.…”

Magnetic nanotubes produced by hydrogen reduction

“…To remove water and fully transform the aluminum, the substrates are preannealed in air at 600°C for 10 min before use. 11 To form the ferrimagnetic Fe 3 O 4 nanotubes, the substrates were wetted with alcohol and loaded with a 65 wt % Fe(NO 3 ) 3 •9H 2 O in alcohol solution at 25°C. This solution was then forced into the template pores at the same temperature using a pressure cell.…”

Nanomagnetic Structures: Fabrication and Interactions

“…The use of porous alumina templates is preferable to other templates such as diblockcopolymers, track-etched polycarbon, porous silicon, and zeolite [13,14] in hydrogen reduction because it is resistant to organic and inorganic compounds, is stable at high temperature, and can easily be removed with an aqueous sodium hydroxide solution.…”

“…This is a generally accepted prototype of a porous alumina template. By carefully controlling the anodization process and structure of the aluminum foil, two-step anodization can create similar structures [13].…”
