| Outline of Final Research Achievements |
The garnet type iron oxide thin films showing spin glass physical properties have been synthesized for the first time by controlling randomness and frustration at atomic scale. In photo-induced spin states, which corresponds to write/erase properties, can be demonstrated using these materials. Enhancement of short-term memory and synaptic behaviors such as adaptive learning are confirmed. Furthermore, we have designed and fabricated semiconducting chips incorporating the biological fluctuation function (stochastic resonance) and successfully verified the signal enhancement effect due to noise.
