| Research Abstract |
We succeeded in the fabrication of ultra high density ferromagnetic nanorod array which density was ranged from 200 Giga to 2.5 Tera per square inch, using porous alumina nanohole array formed on Si substrate. The smallest diameter of nanorod is 10 nm, and the coercivity at room temperature is 2.0 kOe. Furthermore, we succeeded in shrinkage of the ordered nanohole array using a combination of top-down and bottom-up technology, namely, ion beam etching with electron beam lithography and anodic oxidation of aluminum.
