Chiba-Nomura (Hikaru) Lab
Machine-translated · View original
A spintronics lab that uses nanomagnets to measure force and make devices remember it.
AboutAbout the lab
Drawing out the hidden potential of materials.
As a member of the Smart Lab for Nanomaterial Function Creation, the Chiba Lab uses nano ultrathin films and nanomagnets to create new material functions.
The lab focuses on greatly changing the spacing between atoms, which determines the properties of a solid, by using ultrathin films that can stretch and contract.
Centered on magnetic properties, that is, the physical properties of spin, the lab proposes ways to control them and links this work to sensing technology that detects force.
The lab belongs to the International Center for Synchrotron Radiation Innovation Smart, where it works on using NanoTerasu, making use of all kinds of measurement methods, and conducting international collaborative research.
Key terms
- Spintronics
- Technology that uses the magnet-like property of electrons (spin) to record information and operate devices
- Nano Ultrathin Film
- An extremely thin film only nanometers thick (a nanometer is one millionth of a millimeter)
- NanoTerasu
- A 3 GeV high-brilliance synchrotron radiation facility. Its very bright light makes it possible to observe the inside of materials

ResearchResearch themes
At the Smart Lab for Nanomaterial Function Creation, the lab promotes the use of all kinds of measurement methods and international collaborative research in order to create material functions that overturn existing concepts. Centered on stretchable solid nano ultrathin films and nanomagnets, it aims to open up a new academic field.
*Illustrative imageSpin Elastronics
Interatomic spacing is fundamental to determining the properties of a solid. Focusing on stretchable nano ultrathin films, the lab aims to change atomic spacing substantially in a reversible way, and is proposing principles for controlling spin properties and developing mechanical sensing technology.
*Illustrative imageIntelligent Nanomagnets
Nanomagnets are used for information storage. Using their magnetic interactions, the lab is developing devices that can sense forces, remember them, and perform computation without a power supply.
*Illustrative imageMeasurement Technology and Social Implementation
Through these efforts, the lab aims to broaden the range of uses of spintronics in society. By combining NanoTerasu light with other measurement methods, it opens up new uses for measurement and control.
