About awarded research
[About awarded research] Ritsuki Sonetaka, Md Shamim Sarker, EMK Ikball Ahamed, Hiroyasu Yamahara, Hitoshi Tabata, "High-temperature spin cluster glass Lu3Fe5-2xCoxSixO12 and its application for neuromorphic computing", Symposium on Hyper-Ordered Structure Sciences, London, UK, Jan. 2025.
[Research Contents] Spin glasses are magnetic materials in which the spins, very tiny magnets, are fixed in a random direction. Theoretical studies on them have influenced various fields such as associative memory in the brain and machine learning, but few device applications have been reported due to the lack of strong magnetism and very low transition temperatures. In this study, by substituting anisotropic cobalt ions and non-magnetic silicon ions in lutetium iron garnets with strong spin interactions, a spin glass phase was confirmed at room temperature and reservoir computing operation, a type of neuromorphic computing, was successfully demonstrated at room temperature.
Your impression & future plan
I am very honored to receive this award. I would like to express my gratitude to my supervisor, Prof. Tabata, for his guidance and the support of the members of my laboratory. I will continue to work even harder on my research.
