The 50th TI-FRIS Hub Meeting / 66th FRIS Hub Meeting (Hybrid event)

TI-FRIS Hub Meetings are held once a month at Tohoku University to foster researchers who understand and can utilize the importance of interdisciplinary research across disciplines and institutions.
 
Common sense and way of thinking cannot be expected among researchers in different fields. The audience is encouraged to ask questions during the presentation to discuss and deepen their understanding. Please participate actively.

 
 
・Date & Time: Every Friday of the month except August (16:00-17:00)
・Target Audience: TI-FRIS Fellows, researchers and students from TI-FRIS participating institutions

As to the Presenter
 
Presentation Title：Magneto-Optical Devices and Spin-Wave Devices Using Magnetic Garnets
Abstract：
Magneto-optical devices controlling light through magnetism fascinate researchers with their unique characteristics impossible to replicate elsewhere, also drawing significant attention from industry. The starring material in this field is magnetic garnet, a magnetic oxide crystal. I will introduce optical device development using this material, including thin-film Q-switch lasers for mechanical processing, magnetic hologram lenses for pest control, and optical isolators for data centers. My presentation covers material development involving ion beam sputtering, laser heat treatment, epitaxial growth, NanoTerasu synchrotron radiation, and Fugaku supercomputer. Furthermore, I will present spin wave logic devices, magnonic crystals, and magnetic sensors made from these same magnetic garnet materials.
