Saito-Ogawa Lab
Machine-translated · View original
A lab researching next-generation hard disks, iron nitride magnetic powder, and related spin-based materials.
AboutAbout the lab
Exploring spin properties, from magnetic recording to magnetic powder
The Saito-Ogawa Lab belongs to the Ultrafine Electronics Division in the Department of Electronic Engineering, Graduate School of Engineering, Tohoku University.
The research page lists next-generation hard disks, Fe-based spin nanoclusters, magnetic powder for next-generation ICT, and light–spin properties as research themes.
The lab's website posts research videos, mainly as a lab introduction for third-year undergraduates.
Key terms
- perpendicular magnetic recording media
- Recording materials, such as those used in hard disks, in which data is written by aligning the magnetization perpendicular to the recording surface
- iron nitride
- A compound of iron and nitrogen. This lab lists it as a material for magnetic powder (Magpau) for next-generation ICT
- magnetic domain observation microscope
- A microscope that visualizes the distribution of magnetic domains, which are small regions where the magnetization points in the same direction
