| Outline of Final Research Achievements |
We have attempted to efficiently utilize thermal fluctuations and amplify the signal. The key to realizing an excellent stochastic resonance device (power-saving device) is how to efficiently utilize the thermal energy that exists in the environment. We have designed practical devices such as spin pumping, magnonics, and spin wave devices using spin glass materials that mimic biological fluctuation functions (iron ions in garnet-type ferrite oxides are replaced by non-magnetic elements such as Si and Ge, and Co with large magnetic anisotropy).As a result, we found the elemental combination which can realize the spin glassy state at high temperatures above room temperature. In addition, we discovered the memory effect derived from spin glass.
