Spintronics Devices and Materials
update：2022-06-30
Features
Spintronics is a technology utilizing electron spin which provided magnetic sensor, nonvolatile magnetic memory, and so on. Our studies are as below.Noble & Rare-earth free magnetic films with large perpendicular magnetic anisotropy. We achieved to develop various Mn-bases alloy films exhibiting high perpendicular magnetic anisotropy (Fig.1 ).
THz range observation of magnetization motion. We achieved to detect a motion of magnetization using pulse laser in time domain (Fig. 2).
Novel organic spin devices. We achieved to fabricate hybrid junction consisting of an organic layer sandwiched by two inorganic magnetic layers and to observe magnetoresistance effect.
Tunnel Magnetoresistive devices: We are developing TMR devices with Mn-Ga alloys films (Fig.3 ).
Targeted Application(s)/Industry
Magnetic memory and storage. Microwave and Terahertz wave. Magnetic sensors.We hope to conduct collaborative research with a willing company for a practical application of these devices and materials in industry.
