概要
- 論文の詳細を見る
Dynamic magnetic recording properties of Co-filled nanohole arrays were successfully investigated as perpendicular magnetic media via a flying giant-magnetoresistive head. By narrowing the Co nanopillar pitch, we observed suppression of the magnetic transition width and increase of the signal-to-noise ratio. The dynamic signals reflect magnetic field variation caused by the nanopillar arrangement on the tens of nanometers scale. These characteristics and the signal behavior suggest their possible application to ultrahigh-density magnetic recording.
