AboutAbout the lab
Understanding and controlling nanoscale magnetic functions
The Okamoto Lab focuses its research on understanding and controlling magnetic functions at the nanoscale.
Ferromagnets are widely used in information and communications, electronic components, motors, and generators, and the diverse functions of these magnetic devices all arise from spin behavior at the nanoscale.
A recording technology that controls spin behavior in the microwave frequency range is expected to dramatically increase the recording density of hard disks.
The lab also studies methods for controlling the magnetization state at particle surfaces in permanent magnet materials, which are essential for high-performance motors in electric vehicles.
Key terms
- Ferromagnet
- A material, like iron, that is strongly attracted to magnets and can itself become a magnet
- Spin
- A property of electrons that makes them behave like tiny magnets. It is the origin of magnetism in materials
- Permanent magnet
- A magnet that keeps its magnetism without any external force being applied
