AboutAbout the lab
Creating the magnetic materials that support society
The Tezuka-Matsuura Lab researches the magnetic materials that support society.
Magnetic materials are used in many everyday devices, including inductors, magnetic recording devices, magnetic sensors, transformers, speakers, and electric motors.
The lab approaches the subject from two sides: making new materials and improving the functions of existing ones.
Its research themes are functional magnetic materials, spintronics materials, permanent magnet materials, and high-frequency magnetic materials.
Key terms
- Magnetic materials
- Materials that act as magnets or respond strongly to magnetism
- Permanent magnet
- A magnet that keeps its magnetic force without electric current. It is used in motors and speakers
- Spintronics
- A field that controls and merges semiconductor engineering (charge) and magnetic engineering (spin) at the nanoscale
ResearchResearch themes
The lab researches magnetic materials, which are indispensable to daily life, from the perspectives of creating new materials and enhancing their functions. Its themes are functional magnetic materials, spintronics materials, permanent magnet materials, and high-frequency magnetic materials.
*Illustrative imageFunctional magnetic materials
If the properties of the magnetic materials used in everyday life improve, this leads to energy savings and greater comfort. The lab aims to understand the origin of these properties, control samples at the nanoscale to manipulate spin states and interactions, and develop materials with greatly enhanced properties.
*Illustrative imageSpintronics materials
As the digital society advances, new materials and technological innovation based on them are in demand. The lab controls and merges semiconductor engineering (charge) and magnetic engineering (spin) at the nanoscale to create new electronics.
*Illustrative imagePermanent magnet materials
Permanent magnets are materials indispensable to modern society, used in drive motors for electric aircraft and electric vehicles, motors for drones and robots, and speakers and vibration motors in smartphones. They support smaller, more efficient, and more energy-saving devices, and help build a low-CO2-emission society.
*Illustrative imageHigh-frequency magnetic materials
In high-frequency wireless communication such as smartphones and Wi-Fi, which has become higher in capacity and speed, these materials prevent devices from malfunctioning. They support the safe and reliable wireless communication that will be essential to a future society with autonomous driving and telemedicine.
